PROBLEM TO BE SOLVED: To effectively prevent the fall of fixing temperature by providing a 3rd control sequence for consecutively forming an image on the recording paper of the 1st kind of size by controlling a constitution part based on a 2nd control sequence. SOLUTION: An image forming sequence is programmed so that the time to perform copying for three sheets of large-size plain paper may be the same as the time to perform copying for five sheets of small-size plain paper. The copying time for large-size cardboard (A3) is set to be twice as long as that for the large-size plain paper. The copying time for small-size cardboard (A4) is set to be equal to that for the large-size plain paper. By setting the copying time for each copying mode in such a way, the point of time to start forming the image per recording paper is common among different image forming modes. For example, the point of time T2 to start forming the image of the second sheet of the small-size cardboard shown by the sequence a4 coincides with the point of time S1 to form the image of the second sheet of the large-size plain paper shown by the sequence a1. |
