Abstract

감광체에 형성되는 잠상을 각기 다른 색상의 현상제로 현상되는 복수의 현상기를 구비하여 화상을 형성하는 화상 형성장치가 개시되어 있다. 그 장치는 감광체(41B-C)들의 배열방향으로 광을 투사하는 노광용 광학계(30), 그 광을 다른 평행한 경로로 반사시키는 제1이동미러(31), 이 제1이동미러에서 반사된 광을 선택된 감광체로 반사되는 제2이동미러(32)를 구비한다. 제1 및 제2이동미러는 선택된 감광체의 위치와 관계없이 광로의 길이가 일정하도록 이동한다. 따라서 각 감광체에 일정한 크기의 잠상이 형성되는 것이다.Disclosed is an image forming apparatus comprising a plurality of developing devices for developing a latent image formed on a photosensitive member with a developer of different colors to form an image. The apparatus includes an exposure optical system 30 for projecting light in an array direction of the photosensitive members 41B-C, a first moving mirror 31 for reflecting the light in another parallel path, and the light reflected from the first moving mirror. The second moving mirror 32 is reflected to the selected photoconductor. The first and second moving mirrors move so that the length of the optical path is constant regardless of the position of the selected photosensitive member. Therefore, a latent image of a certain size is formed on each photoconductor.
