Abstract
An electrophotographic copying machine includes a photoreceptor for forming a latent image of a copy document, a transfer corona charger for transferring the latent image onto a copy document, a separation corona discharger for removing charges from the copy paper, and aid in the separation of the copy paper from the latent image. The corona discharge output of the separation corona discharger is adjustably changed depending on an amount of light reflected by the copy document to more effectively provide for the separation process.
