Abstract
A copy paper separator is disposed opposite to a surface of a photosensitive body in an electrophotographic copying machine. A transfer charger for transferring images to copy paper and a separation charger for helping the paper to separate from the photosensitive body are adjacent to each other. A sheet made of a narrow belt-like insulator is disposed between the separation charger wire and the photosensitive body and an insulative plate is disposed at the boundary between chargers such that the copy paper can be effectively separated.
