Bilderzeugungsgerät mit Steuerung der Lichtmenge von mindestens zwei Laserstrahlen

摘要

An image forming apparatus (1) includes an image bearing member (6), a latent image writing device (4) that emits a plurality of laser beams, at least two adjacent laser beams of which are partially overlapped in a sub-scanning direction, and that forms a latent image of a reference image on a surface of the image bearing member (6) by performing a repeated scanning of each laser beam forming the latent image of the reference image on the surface of the image bearing member 6, a developing device (8) that develops the latent image of the reference image on the surface of the image bearing member (6) with toner into a toner image of the reference image, and a detecting device (100) that detects the density of the toner image of the reference image on the image bearing member (6). The latent image writing device (4) has a plurality of modes of writing the latent image of the reference image. The quantity of light of each laser beam forming a subsequent latent image is adjusted according to the density of the toner image of the reference image detected by the detecting device (100). <IMAGE>
