Abstract
Copying apparatus is constituted by a photosensitive member having a photochromic characteristic when changes light transmitibility when projected with light reflected by a manuscript. A light source is provided for projecting a photo-image formed on the photosensitive member onto a photosensitive recording sheet through the photosensitive member. In a modified embodiment, the copying apparatus has a construction substantially the same as the conventional electrophotographic copying machine except that a photosensitive drum is made of transparent material and covered by a thin transparent photoconductor. Consequently a toner image corresponding to the photo-image of a manuscript is formed on the photosensitive drum. A light source is provided for projecting the toner image on a photosensitive recording sheet.
