摘要：<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus which stably forms a high quality image. <P>SOLUTION: The image forming apparatus includes: four photoreceptor drums; four light sources (2200a, 2200b, 2200c, and 2200d); a polygon mirror 2104 which deflects a luminous flux from each light source; and a scanning optical system which forms a latent image by condensing each luminous flux, deflected by the polygon mirror 2104, onto the corresponding photoreceptor drum; four developing devices each of which attaches toner to the corresponding latent image, thereby forming a toner image; a transfer roller for transferring the toner image to recording paper; and a fixing device which fixes the toner image, transferred to the recording paper, to the recording paper. The polygon mirror 2104 rotates around an axis parallel to Z axis and in the same direction as the direction directing from the light source 2200d farthest from the fixing device among the four light sources to the light source 2200b closest to the fixing device. <P>COPYRIGHT: (C)2010,JPO&INPIT
