Abstract

PURPOSE:To easily erase an image in a desirable specified area by executing necessary electrification to the latent image area of an image carrier corresponding to the area of the original which should be erased by an erasing electrifier. CONSTITUTION:The erasing electrifier having non-image areas I-III whose widths are W1-W3 in accordance with the size of a transfer sheet and whose lengths are H1-H3 shorter than an effective image area (l) according to selected grids G1-G7 is provided between an image exposing position and a developing unit. When the electrifier is connected to be earthed through the grids G1-G7 so as to be in an acting state, the desirable latent image area of a photosensitive drum is electrified so that the surface potential becomes high and the latent image can be erased. With such a constitution, the image in the desirable specified area can be easily erased.
