The toner layer thickness regulating member is formed by a toner layer thickness regulating roller that rotates in contact with the cleaning roller. | 06-30-2011 |
| 20110229234 | CLEANING DEVICE AND IMAGE FORMING APPARATUS - There is provided a pre-cleaning brush roller being a pre-cleaning member which is disposed on an upstream of a normally-charged-toner cleaning brush roller and an oppositely-charged-toner cleaning brush roller in a surface moving direction of an intermediate transfer belt, is applied with a voltage having a polarity opposite to a normal charge polarity of toner, and electrostatically removes the toner having the normal charge polarity. | 09-22-2011 |
| 20110243625 | IMAGE FORMING APPARATUS, CLEANING APPARATUS, AND CLEANING METHOD - According to one embodiment, an image forming apparatus includes a foreign-matter removing roller arranged in a post-process of a transfer device. The foreign-mater removing roller includes a rotatable metal shaft and a cylindrical conductive first sponge attached to the outer circumference of the metal shaft. The foreign-matter removing roller is attached a fixed distance apart from the surface of an image carrier and electrostatically attracts foreign matters adhering to the image carrier. A cleaning member scrapes off the foreign matters attracted by the foreign-matter removing roller. | 10-06-2011 |
| 20120195664 | IMAGE FORMING APPARATUS - When the acute angle between a normal line, oriented outward from a blade abutting portion of a photosensitive member over which a cleaning blade remains abutted before separation of the surface of the photosensitive member from the cleaning blade, and a horizontal plane, passing through the origin of the normal line, is expressed as a positive value when the normal line lies above the horizontal plane and expressed as a negative value when the normal line lies below the horizontal plane; an imaging unit frame so supports a photosensitive module that the photosensitive member can rotate to a specific rotational position having a greater angle than the angle at the time of separation of the surface of the photosensitive member from the cleaning blade. Until the photosensitive member rotates from a normal rotational position to the specific rotational position, the photosensitive module cannot be removed from the imaging unit frame. | 08-02-2012 |
