摘要： PROBLEM TO BE SOLVED: To provide an image of high image quality with an image forming apparatus using a combination of an electrophotographic photoreceptor of a predetermined configuration and a toner by a specific manufacturing method. SOLUTION: The electrophotographic photoreceptor is obtained by stacking a charge generating layer 435 in which charge generating regions containing a charge generating material are dispersedly formed in a minute dot shape and a charge transport layer 437 containing a charge transport material in this order on a conductive support 431. The dispersed formation of the charge generating regions is carried out by jetting a coating liquid for the charge generating layer by a piezo system ink jet process. The space factor of the charge generating regions in the charge generating layer is set to a predetermined value of ≤90% and the dot pitch of the charge generating regions is made equal to the resolution of the image forming apparatus. The toner is obtained by suspension-polymerizing a polymerizable composition comprising a polymerizable monomer and a colorant in an aqueous medium. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To prevent image scatter caused by pre-transfer during intermediate transfer of an image from an image carrier to an intermediate transfer body, even in a case where a counter bias is applied to a part that is upstream of an intermediate transfer nip and the potential of an image part with toner attached to the surface of an image carrier includes residual potential. SOLUTION: The counter bias blade 35 is disposed in the upstream of and near to the intermediate transfer nip Nt in the direction of the movement of the surface of an intermediate transfer belt so that the leading end of the blade 35 comes into contact with the rear of the intermediate transfer belt. A counter bias (Vt) applied to the counter bias blade has a value that is shifted from the image part potential to a base part potential. This restricts transfer scatter in the course of intermediate transfer. COPYRIGHT: (C)2004,JPO
