<P>PROBLEM TO BE SOLVED: To detect toner adhesion amount without particularly using a means for detecting toner adhesion amount on an image plane, to shorten fixing warm-up time, and to drastically shorten image optimizing control time required as preparation time at the time of starting. <P>SOLUTION: The image forming apparatus has an electrifying means, an exposure means, a developing means, and a cleaning means arranged on a photoreceptor and on the periphery thereof, and has a primary transfer means which the photoreceptor directly comes into contact with so as to primarily transfer a toner image formed on the photoreceptor to transfer material and fixing means. In the apparatus, the adhesion amount of toner is detected from an output voltage value generated in a power source in the case of applying voltage to the primary transfer means or an output current value flowing to the primary transfer means. <P>COPYRIGHT: (C)2004,JPO |
