Patent attributes
A printer has a laser emitter for emitting a laser beam to irradiate a surface of a photosensitive member; a reflector, disposed at a position on a laser beam path defined by the laser emitter and the photosensitive member, for reflecting the laser beam emitted by the laser emitter to direct the reflected laser beam to a target position on the surface of the photosensitive member; a reflective mirror driver for reciprocating the reflector in such a manner that the laser beam travels along a scanning line on the surface of the photosensitive member in a direction for scanning; and an emission controller for controlling the laser emitter to selectively emit the laser beam along the scanning line in the forward direction or the backward direction defined by the movement of the reflector driven by the reflective mirror driver.
