PROBLEM TO BE SOLVED: To prevent an image flowing, even in the case of successive printing for the long time or printing of the low printing ratio image, under the high temp./high humidity environment, while preventing an enlargement of device and an increase in cost. SOLUTION: This device is allowed to store the rotating time of a photoreceptor drum 1, printing ratio of the printed image, the number of sheets of recording paper 17 successively printed, and the number of sheets intermittently printed, transmitted from a CPU 181 to a nonvolatile memory 182. Then, the CPU 181, based on information stored in the non-volatile memory 182, when judging that the image flowing is liable to occur, after the detection signal of the paper discharge sensor 21 is over and completion of the image forming process is judged, is allowed to make the succeeding rotation longer than the ordinary time. |
