Abstract

PURPOSE:To achieve high-density recording with superior resolution by scanning at least either one of a light emitting element array with large light emission surfaces and an imaging element array forth and back in parallel to a photosensitive surface. CONSTITUTION:Emitted luminou flux from an LED12 with large light emission area is reduced to (m) time (m=a/b) through an imaging lens 13 to form an image on a photosensitive surface 14. The extent (d) of the movement of the lens 13 is c/1+m, where (c) is the pitch of the LED12. Further, the irradiation area Si of an imaging part is m<2>So, where So is the light emission area of the LED12. Namely, magnification (m) is determined by the So and necessary resolution to be found, i.e., the irradiation area Si of the imaging part, and the extent (d) of the movement of the imaging lens 13 is determined by the pitch (c) of the LED12 and pitch (c). Under said conditions, the lens 13 is moved at a constant speed by the distance (d) in a main scanning direction E to expose the light emission pattern of the LED12 to the photosensitive surface with the same width F with the pitch (c).
