ABSTRACT:
An image forming apparatus includes a drum having a hollow polyhedron cylinder of which facets have windows. A liquid crystal cell is attached to each window of the drum for receiving image light from out side the drum on the one surface thereof to pick up a document image therein, and for receiving second light on the back surface thereof inside the drum to cause the image to be read out. The drum is rotated so that the liquid crystal cell provided on each window of the drum can sequentially receive first light reflected by the document on the one surface thereof out side the drum and second light irradiated by a second irradiating device on the back surface thereof inside the drum. A photoreceptor for receiving second light reflected by the back surface of the liquid crystal cell forms an electrostatic latent image corresponding to a document image, which is developed, transferred onto a copy paper and fixed.
