Abstract

PURPOSE: To surely eliminate the adhesion of toner to an area outside the width of supplied paper, by forming the timing signal of a part to be erased on the basis of memory data by a counter means and performing erasure writing by a writing control means.
CONSTITUTION: A register group 3 is constituted of ten kinds of 15 registers A, B, CA, CB, D, E, F, TM, ST, TPH0, TPH1, TPT0, TPV1, ERS0, ERS1 and data NERS0, NERS1 for forcibly performing the erasure writing of the part of a photosensitive body corresponding to the difference between the max width of the paper capable of being fed to a paper feeder and that of actually used paper are stored in the registers ERS0, ERS1 and, on the basis of said memory data, the timing signal of a part to be erased is formed by an erasure counter/ control circuit 5 and white data is forcibly written on both left and right end parts or the right end part by an LD control circuit 13. Therefore, the adhesion of toner to an area outside the width of supplied paper can be surely eliminated.
