PURPOSE: To obtain an image of high quality by providing a support member parallel with developing rollers and opposite developing devices with a photoreceptor between them, thereby stabilizing the contact of the photoreceptor and developing rollers and making development color by color uniform. CONSTITUTION: A drive roller 103, a follower roller 104, the developing rollers 111Y, 111M, 111C, and 111B and a flexure correction shaft 1 are arranged so that when the photoreceptor 101 and the developing rollers 111Y, 111M, 111C, and 111B are in contact, the states of the developing rollers 111Y, 111M, 111C, and 111B being in contact with the photoreceptor 101 are the same. That is, by arranging the drive roller 103, follower roller 104, developing rollers 111Y, 111M, 111C and 111B and flexure correction shaft 1 with the specific distance relationship maintained between them, the contact of the photoreceptor 101 and the developing rollers 111Y, 111M, 111C, and 111B is stabilized, and because development color by color is made uniform, an image of high quality can be obtained. |
