PROBLEM TO BE SOLVED: To provide an image forming apparatus that can uniform particles irregularly depositing on the surface of a photoreceptor to suppress electrifying irregularity by reciprocating a conductive brush with respect to the photoreceptor surface and can maintain excellent image characteristics for a long period even when a contact electrification system is employed as a electrifying means, and to provide an image forming method using the apparatus. SOLUTION: In the image forming apparatus, in which an electrifying means, a developing means, a transfer means and a destaticizing means are sequentially arranged around an electrophotographic photoreceptor, the electrifying means is a contact type electrifying means, a uniforming means to uniformize particles on the surface of the electrophotographic photoreceptor is arranged between the electrifying means and the destaticizing means, and the uniforming means comprises a conductive brush in contact with the surface of the electrophotographic photoreceptor and a reciprocating means to reciprocate the conductive brush in a direction orthogonal to the rotation direction of the photoreceptor. The amplitude of the reciprocation is controlled to≥1 (mm). COPYRIGHT: (C)2007,JPO&INPIT |
