An image forming apparatus includes an image forming unit, an image receiving unit, an aggregate printing process unit, a size receiving unit, a size judgment unit, and an aggregate sheet number determination unit. In the case where the size judgment unit judges that an aggregate printing process is executable in such a manner that the smallest size (aggregate smallest size) of characters included in an aggregate print image formed on a sheet by the aggregate printing process is not smaller than the lower limit value (lower limit size) of the size of characters included in the aggregate print image received by the size receiving unit, the aggregate sheet number determination unit determines the aggregate sheet number in such a manner that the aggregate smallest size is not smaller than the lower limit size, and the aggregate printing process unit executes the aggregate printing process using the aggregate sheet number. |

1. An image forming apparatus, comprising:
a display unit configured to display information; an image forming unit configured to form an image on a sheet; an image receiving unit configured to receive the image including characters; an aggregate printing process unit configured to execute an aggregate printing process of aggregating received character images received by the image receiving unit and causing the image forming unit to form an aggregate print image on one of sheets; a sheet number detection unit configured to detect the number of sheets having the received character images; a size extracting unit configured to extract a size of a smallest one of characters included in the received character images; a size input guiding unit configured to prompt a user to input a lower limit value by causing the display unit to display:
a first operation screen including an extracted smallest size that is extracted by the size extracting unit and is the size of the smallest one of the characters,a first message prompting the user to input the lower limit value, anda first input area of the lower limit value; a size receiving unit configured to receive the lower limit value that is input through the first input area; a size judgment unit configured to judge that the aggregate printing process is executable, in the case where a lower limit size, being the lower limit value received by the size receiving unit, is smaller than the extracted smallest size and the case where the aggregate printing process is executable in such a manner that an aggregate smallest size is not smaller than the lower limit size, the aggregate smallest size being a size of the smallest one of characters included in the aggregate print image; an aggregate sheet number determination unit configured to execute an aggregate sheet number determination process of determining an aggregate sheet number in such a manner that the aggregate smallest size is not smaller than the lower limit size, in the case where the size judgment unit judges that the aggregate printing process is executable, the aggregate sheet number being the number of sheets of images to be aggregated on one of sheets by the aggregate printing process; a sheet number receiving unit configured to cause the display unit to display:
a second operation screen including the number of sheets having the received character images detected by the sheet number detection unit,a second message prompting the user to input an upper limit value for the number of sheets to be used in the aggregate printing process, anda second input area of the upper limit value, the sheet number receiving unit further being configured to receive the upper limit value input in the second input area in the case where:the size judgment unit judges that the aggregate printing process is executable,the number of sheets having the received character images detected by the sheet number detection unit is two or more, andthe user has selected that the upper limit value is designated; a sheet number judgment unit configured to judge that the aggregate printing process is executable when the number of sheets to be used in the aggregate printing process using the aggregate sheet number determined by the aggregate sheet number determination unit is not larger than an upper limit sheet number in the case where the upper limit value is received by the sheet number receiving unit, the upper limit sheet number being the upper limit value received by the sheet number receiving unit; and a selection instruction receiving unit configured to selectively receive an instruction to prioritize the lower limit size, and an instruction to prioritize the upper limit sheet number, in the case where the sheet number judgment unit judges that the aggregate printing process is inexecutable, wherein: the aggregate printing process unit executes the aggregate printing process using the aggregate sheet number determined by the aggregate sheet number determination unit, in the case where the size judgment unit judges that: the aggregate printing process is executable, the number of sheets having received the received character images detected by the sheet number detection unit is two or more, and the user has selected that the upper limit value is not designated, the size input guiding unit prompts the user to input the lower limit value again, in the case where the size judgment unit judges that the aggregate printing process is inexecutable, the aggregate printing process unit executes the aggregate printing process using the aggregate sheet number determined by the aggregate sheet number determination unit, in the case where the sheet number judgment unit judges that the aggregate printing process is executable, the aggregate sheet number determination unit determines the aggregate sheet number again in such a manner that the number of sheets to be used in the aggregate printing process is not larger than the upper limit sheet number, in the case where the selection instruction receiving unit receives the instruction to prioritize the upper limit sheet number, and the aggregate printing process unit executes the aggregate printing process using the aggregate sheet number determined by the aggregate sheet number determination unit in the case where the selection instruction receiving unit receives the instruction to prioritize the lower limit size, and executes the aggregate printing process using the aggregate sheet number determined again by the aggregate sheet number determination unit in the case where the selection instruction receiving unit receives the instruction to prioritize the upper limit sheet number. |
