摘要： An apparatus provided with a first reflector for reflecting a light beam deflected by a deflector in a light beam scanning apparatus and a second reflector for directing the light beam from the first reflector toward an image forming point after contacting again the first reflector. The light beam is reciprocated between the first and second reflectors thereby forming a light path of two times the space that they are disposed. A deflector is disposed on a side of the light path extending from the first reflector to the light beam image forming point together with a light beam emitting source which irradiate the light beam on the same level of the light path and make the light path length at both ends of the light beam scanning range equal to each other by arranging an angle between the first and second reflectors.

In this apparatus, an image is formed selectively in a print mode so that an image results from turning on and off the laser beam, in a copy mode that a copy of an original results from exposure of the photosensitive member to the laser beam reflected from the surface of an original or in a composite mode that a composite image is formed of a copy of an original and an image resulting from turning on and off the laser beam. Further, this apparatus comprises a projection lens unit for projecting an image reflected from an original onto the photosensitive member. The laser beam transmitting through the lens unit is scanned in the direction perpendicular to the main scanning direction, and altering the scanning speed and position of the lens unit results in various magnifications of an image.
