ABSTRACT:
A copying apparatus, having an editing function, charges a rotating photoconductive drum 61 by chargers 63 and 65 and forms an electrostatic latent image on the photoconductive drum 61 by projecting an image of a document on the drum 61, whereby the electrostatic latent image is developed by toner. An erasure array 4 including LED elements is provided close to the photoconductive drum 61. In an edit copy mode, data for specifying a region to be copied on the document is inputted by using keys on an operation panel. As a result, the erasure array 4 removes the electric charge on a region of the photoconductive drum 61 corresponding to the specified region prior to exposure, whereby the electrostatic latent image can be prevented from being formed on this region. At this time, a control apparatus controls the extent of emission of light of the erasure array 4 and the timing for the emission of light of the erasure array 4 based on the input data, thereby to prevent occurrence of deviation in boundary portions of the region defined in the edit copy mode.
