IPC: G03G5/07
Filed: 1995-04-14
Abstract: PURPOSE: To continuously produce an electrophotographic photoreceptor in a high yield by forming a carrier generating layer by vacuum deposition on an electrically conductive substrate and further forming an electric charge transferring layer with an electric charge transferring polymer formed by a vacuum deposition-polymn. method. CONSTITUTION: The shutter 17a of an evaporation boat 17 is opened and a material for a carrier generating layer, e.g. TiO.Pc put in the boat 17 is vacuum-deposited on the surface of a rotating substrate 14. At the time when a prescribed film thickness is attained, the shutter 17a is closed and a carrier generating layer of the prescribed film thickness is formed on the surface of the substrate 14. First and second monomers for vacuum deposition and polymn. separately put in evaporation boats 15, 16 are then vauum-deposited on the surface of the rotating substrate 14. At this time, the monomers cause a polymn. reaction on the substrate 14 to form an electric charge transferring polymer and a carrier transferring layer is formed on the carrier generating layer on the surface of the substrate 14.

Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To focus at a desired position by arranging point light sources on a substrate based on the optical characteristics including the strain aberration of a focus lens system such that the images of respective light sources are arranged as required at the focal points on an image face thereby compensating for the aberration. SOLUTION: Prior to the work for arranging LED chips 208M on a substrate 210, a model of a system for actually recording an image is prepared and the LED chips 208M are lighted at a theoretical pitch of arrangement. The distances from the center of a lens to an actual imaging point and to a theoretical imaging point at least one LED chip 208M farthest from the optical axis are then determined. With reference to the difference of the distanced thus determined, arranging position of an LED chip 210 is shifted reversely to the direction of displacement due to strain aberration depending on the difference between the theoretical value and an actual value of other LED chips. Since the LED chips 210M are arranged in spool shape on the substrate 210M, strain aberration on the image face is canceled.
