Abstract
In a copying apparatus employing a light source for illuminating an original subject to be copied and forming a toner image corresponding to said original subject on a recording medium, a solid imaging device is employed for converting a reflected light from the original subject into electric charge and storing the electric charge therein. The solid imaging device is provided with a chargeable surface on which the electric charge is to be collected. By applying a toner onto the charged portion of the surface of the solid imaging device, an image on the original subject is copied repeatedly, with a single exposure system for illuminating the original subject.
