<P>PROBLEM TO BE SOLVED: To prevent developing accuracy from being deteriorated and to prevent a developer carrier and a latent image carrier from being damaged. <P>SOLUTION: By satisfying first and second conditions simultaneously, developer 32 is made to lie on an entire abutting part between a photoreceptor and a developing roller 31, so that a surface of the photoreceptor or the developing roller 31 is prevented from being damaged. By satisfying a third condition, the unnecessary developer 32 on the photoreceptor is all removed finely before developing an electrostatic latent image formed in an image area on the photoreceptor by the developing roller 31, so that the unnecessary developer 32 is prevented from remaining and being accumulated on the photoreceptor. The developing accuracy is therefore prevented from being deteriorated, for example, ghost is caused by accumulation of the useless developer 32 on the photoreceptor. <P>COPYRIGHT: (C)2011,JPO&INPIT |
