ABSTRACT:
An image forming device including a photosensitive drum having a first motor disposed to rotate the photosensitive drum at a speed Vp; an optical unit disposed to create a charged pattern corresponding to an original image on the photosensitive drum; a revolver developing device disposed to apply developer to the photosensitive drum to create a visible image on the photosensitive drum, the revolver developing device including a second motor disposed to rotate the revolver developing device at a speed Vr, a plurality of developing devices each having a developing roller for carrying developer, and a third motor disposed to rotate the developing roller of each developing device at a speed Vs, wherein Vr+Vs-Vp.noteq.0 such that the rotation speed of each developing roller is determined so that the developer on the developing roller moves relatively in a direction of a tangent line of the developing roller against the surface of the photosensitive drum when the developer on the developing roller comes separate from the developing roller and comes in contact with the photosensitive drum; and a transfer system disposed to transfer the visible image to a sheet.
