Abstract

PURPOSE:To prevent the deterioration of a image forming efficiency due to uneven scanning, by placing a lens array in >=2 rows so that image forming patterns by each lens array are overlapped to each other, in an image forming device using a platelike lens on which a lot of lens elements have been placed in a row. CONSTITUTION:A light beam from a body 27 is divided into 2 directions through a half-mirror 23. The light beam which has passed through forms an image on an image surface 21 through a lens array B. The reflected ray is reflected by a reflector 24, passes through an array A, and forms an image on the same image surface 21 through a reflector 26 and a half-mirror 25. Pitches of image forming elements of each lens array are shifted from each other by a half-pitch, but on the image surface 21, images of the respective lens arrays are greatly overlapped on each other.
