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 |

The detector is adapted to detect an absolute humidity around the lubricant supply device. The varying device is adapted to vary an amount of the lubricant to be supplied to the toner image bearing member based on the absolute humidity detected by the detector. | 12-13-2012 |
20120321330 | LUBRICANT SUPPLYING DEVICE, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS - A lubricant supplying device includes a lubricant supplying roller configured to rotate in a certain direction and makes a sliding contact with an image carrier on which a toner image is carried; a solid lubricant arranged to slide in contact with the lubricant supplying roller; a changing unit configured to change a revolution of the lubricant supplying roller to adjust an amount of the solid lubricant supplied onto the image carrier; and a calculation unit configured to obtain a product life or total consumption of the solid lubricant from a total running distance or total operating time of the image carrier or the lubricant supplying roller, the product life or the total consumption of the solid lubricant being corrected based on the amount of the solid lubricant supplied onto the image carrier. | 12-20-2012 |
20120328332 | IMAGE FORMING APPARATUS WITH NEUTRALIZER AND IMAGE FORMING METHOD - An image forming apparatus including an image bearing member, a charger, an irradiator, a developing device, a transfer device, a neutralizer, and a varying device is provided. The neutralizer is adapted to neutralize the image bearing member by emitting neutralization light thereto, after a toner image formed on the image bearing member is transferred therefrom. The varying device is adapted to vary an amount of the neutralization light to be emitted to the image bearing member by pulse-width modulation of a voltage to be supplied to the neutralizer. The image forming apparatus satisfies the following formula: | 12-27-2012 |
