发明名称 Illumination control means for image forming apparatus
摘要 The present invention provides an image forming apparatus comprising a photosensitive member, scan means including light emitting elements for emitting laser beam to scan the photosensitive member, and control means for controlling the illumination of the light emitting elements. Wherein, when a shifting speed of the laser beam on the photosensitive member is v, a length of one side of a pixel is L and a maximum light emitting time of the light emitting element for each pixel is t, the control means controls the light emitting elements to satisfy a relation of t<L/v.
