<P>PROBLEM TO BE SOLVED: To remove foreign materials caught between a regulating member and a developing roller without requiring a special mechanism. <P>SOLUTION: A motion-determining unit 84 determines whether or not a current state of a color printer 1 is in a motion state for non-image formation. When the motion-determining unit determines that the color printer 1 is in the operation state for non-image formation, a feed rate-adjusting unit 85 adjusts the feed rate of a developer that a supply roller 202 supplies to the developing roller 201, so that a higher amount of the developer than the feed rate of the developer to be supplied to the developing roller 201 at the time of the operation of image formation is supplied to the developing roller 201. <P>COPYRIGHT: (C)2010,JPO&INPIT |
