<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus controlled to provide a satisfactory transferred image even if contaminations of a large particle size is present in toner images on a photoreceptor or an intermediate transfer member, by improving transfer failure caused by non-contact of toner around the coarse particles to a member to be transferred when the coarse particles of a carrier or the toner exist on the photoreceptor. <P>SOLUTION: In this image forming apparatus provided with the photoreceptor, the intermediate transfer member consisting of semi-conductive resin, a binary developing device consisting of the toner and carrier, and a primary transfer means transferring the toner on the photoreceptor to the intermediate transfer member, conditions of the primary transfer means transferring from the photoreceptor to the intermediate transfer member are controlled depending on an amount of charge of the toner on the photoreceptor. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
