Title: Image forming device
Inventor: AKAFUJI MASAHIKO
IPC: G03G21/14
Filed: 2000-07-14
Abstract: PROBLEM TO BE SOLVED: To prevent image blur resulting from attachment of discharge product to an image carrier, in an image forming device which stops the image carrier during a quiescent period of an image forming operation in such a manner that a toner carry area on the surface of the image carrier is opposed to a charging device and which employs a cleanerless system. SOLUTION: When the image forming operation is brought into a quiescent state, a transfer roller 20 is separated from a photoreceptor drum 10, and the photoreceptor drum is allowed to make one rotation again to provide the uniform toner carry area T over the entire surface of the photoreceptor. An image carrier stop position control means controls drive of the photoreceptor drum only for time required for the toner carry area to reach the position opposite to a grid electrode 11c of the charging device, and stops the toner carry area at the position opposite to the grid electrode. This prevents image blur from being caused due to direct attachment of discharge product to the surface of the photoreceptor by interposing a toner layer between the charging and the photoreceptor.

Title: Charge transfer device
Inventor: BOKU YO
IPC: H01L27/148
Filed: 2000-07-21
Abstract: PROBLEM TO BE SOLVED: To improve charge transfer efficiency and to improve picture quality by dividing a horizontal charge transfer area into plural channels parallel to a transfer direction and making the potential of adjacent channels to be sequentially lower with a prescribed channel having maximum potential as a reference at the time of transferring charge. SOLUTION: For improving the charge transfer efficiency of a horizontal charge transfer area 42, a well area 43 formed in a semiconductor substrate 1 is not formed to be constant for whole width where the horizontal charge transfer area 42 is formed but the well area 43 is formed by separating it into plural parts 43a to 43e in parallel to a charge transfer direction. For forming the well area 43 by separating it, the potential of the horizontal charge transfer area has a difference in a width direction owing to a separated distance between the well areas, namely, a difference between one well area and the other well area adjacent to it. Thus, the charge of less quantity can be transferred by not using the massive charge transfer area but using a part of it.
