Abstract

PURPOSE:To make the device small in size, by commonly using light source for information read and image forming. CONSTITUTION:Since a rotary polyhedral mirror 2 rotated with a motor M has reflection surfaces 22, 23 with different slope alternately, one laser beam can be reflected and scanned to different planes A, B. Light toward A is given to a photo electric conversion element 8 via a lens 3a, fixed mirror 4, moving mirrors 5, 6, scans the surface information of an original 7 for reading. The light toward B exposes the surface of a photoreceptor drum 1 via a lens 3a, fixed mirror 4', form an electrostatic image and is recorded and printed on a copy paper 11 and discharged on a tray 14. Thus, since one laser beam is used for original reading and electrostatic image formation, a buffer memory storing read image information can remarkably be reduced or omitted.
