<P>PROBLEM TO BE SOLVED: To provide a developing device that can prevent an image roughness, decrease in density, fogging, etc., resulting from selective development without altering the composition of a developer and main body constitution and form excellent images without shortening the life of an image carrier. <P>SOLUTION: When no image is formed, a DC voltage applied to a developing rotary body 41 is made different from a voltage in normal image formation to discharge a developer inverted in polarity. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
