<P>PROBLEM TO BE SOLVED: To set conditions that satisfactory transfer can surely be performed over a long period. <P>SOLUTION: An auxiliary transfer means for operating a transfer material so as to come into contact with an image carrier is arranged in a transfer means, and in order to control a timing of pressing/releasing the auxiliary transfer means to/from the image carrier, a control part controls a pressure operation starting timing and a release operation starting timing through a timer when the leading/trailing ends of the transfer material are detected by the transport detection sensor positioned closest to a transfer position, and the pressure operation starting timing value and the release operation starting timing value are made variable in terms of time by operating an operating part. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
