IMAGE FORMING METHOD BY POWDER TONER

摘要

PROBLEM TO BE SOLVED: To provide a nonmagnetic one component development method which is excellent in image quality and reduces toner consumption per page. SOLUTION: A developer is supplied to a photoreceptor and the electrostatic latent image on this photoreceptor is developed to a sensible image by using a nonmagnetic one component development device having at least a developer carrying roll and a layer forming member. In such a case, spherical toners having a volume average grain size of 2 to 6μm are used as the developer. The toner adhesion on the developer carrying roll is specified to a range from >=0.1 mg/cm<2> to <=0.45 mg/cm<2> .
