IPC: G03G15/09
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a toner ring on an image carrier by forming a conductive layer electrically caused to be in a floating state in parts on the image carrier corresponding to both ends of a developer magnetic brush. SOLUTION: A photosensitive drum 600 as an image carrier has a conductive layer 695 electrically caused to be in a floating state formed in the most surface layer of parts equivalent to both end parts of a developer magnetic brush 604a in the circumferential direction of the photosensitive body. The conductive layer 695 is formed in such a manner that a part of its width is brought into contact with the end part of the developer magnetic brush 604a and the remaining part of the width is not brought into contact therewith. During impressing of a developing bias to a developing sleeve 623, the entire part of the developer magnetic brush 604a is placed under the same potential as the developing sleeve 623.  Thus, since there is no potential difference between the end part of the developer magnetic brush 604a and the conductive layer 695 part, jumping and sticking of toner to the developer magnetic brush non-contact region (non-charged part) of the photosensitive body 601 are prevented.
