PURPOSE:To easily and positively judge the end of printing by judging the end of printing based on a detection result of a transfer state detection means and a detection result of a data quantity detection means when a printing paper is discharged. CONSTITUTION:On an image forming device provided with a print data memory means A for storing data transferred from the external and a print means B for conducting a printing on paper per page using the print data stored in the print data memory means A, the following means are mounted: a transfer state detection means C for detecting the transfer state of the print data transferred from the external; a data quantity detection means D for detecting the quantity of the print data stored in the print data memory means A; and a judging means E for judging the end of printing based on a detection result of the transfer state detection means C and, a detection result of the data quantity detection means D when a printing paper is discharged. |
