Abstract

PURPOSE:To prevent the outer edge part of a copy from the formation of a black frame at the copying of bookbound-original by erasing an electrostatic latent image formed on a photosensitive drum by lighting blank lamps which is much than the proper number of lamps. CONSTITUTION:A microcomputer 5 controls a driver 5 in accordance with a copying paper size signal or an original size signal and an original kind signal to light up blank lamps which are much by one than the proper number of lamps corresponding to the size of the original out of plural blank lamps b1-b22 during a prescribed period in the exposure of the original. Consequently, an unnecessary latent image including a white part on the outer edge part of the original which is formed on the photosensitive drum is erased, so that the outer edge part of a copy is prevented from the formation of a black frame at the copying of the bookbound-original.
