<P>PROBLEM TO BE SOLVED: To obtain a satisfactory image by performing satisfactory electrification even when consecutively forming high duty images in large quantity. <P>SOLUTION: In a contact electrification system where developer contains electrification auxiliary particles and the electrification auxiliary particles are interposed, when high duty images are consecutively formed in large quantity, most of the electrification auxiliary particles to be developed mainly in an image non-formation area is hardly supplied to the electrifying member and, as a result, electrification failure occurs. Prior to it, an interval between sheets is increased and a large quantity of electrification auxiliary particles present between the sheets is supplied to the electrifying member. <P>COPYRIGHT: (C)2003,JPO |
