| 20100052242 | WARPAGE LEVELING UNIT, WARPAGE LEVELING DEVICE, IMAGE FORMING APPARATUS AND WARPAGE LEVELING PROCESSING PROGRAM - A warpage leveling unit includes a surface roughening member that is provided to oppose to a side end portion of an image carrier which has an endless-belt-shape, is entrained around a plurality of rollers, and carries an image on a surface of the image carrier, wherein the surface roughening member comes into contact with a surface of the side end portion which is warped. | 03-04-2010 |
| 20100150588 | PRIMARY TRANSFER DEVICE AND IMAGE FORMING APPARATUS HAVING THE SAME - A primary transfer device includes a primary transfer roll that is capable of being engaged with and disengaged from an intermediate transfer member to which a developer image is primarily transferred; and a setting-changing unit that changes a setting of pressure of the primary transfer roll to the intermediate transfer member in accordance with kind of a recording medium to which the developer image is secondarily transferred, wherein the setting-changing unit has an irregular medium transfer mode for a case where the recording medium to which the developer image is a recording medium having irregularities formed on a surface thereof, and an ordinary transfer mode for a case where the recording medium is a recording medium other than the recording medium having the irregularities, wherein a pressure set in the irregular medium transfer mode is smaller than that set in the ordinary transfer mode. | 06-17-2010 |
| 20100196032 | IMAGE FORMING APPARATUS - An image forming apparatus includes: an image carrier that carries a developed image that has been developed on a surface thereof using a developer; a transfer member that transfers the developed image from the image carrier to a belt-shaped member; an electric power supply unit that supplies electric power to the transfer member; a measurement unit that measures a combined resistance value of the image carrier, the belt-shaped member, and the transfer member; and a controller that controls the electric power supply unit. The controller controls the electric power supply unit such that the electric power supplied to the transfer member is changed from a predetermined first supply value to a second supply value, the second supply value being larger than the first supply value, when the combined resistance value measured by the measurement unit is lower than a predetermined combined resistance value. | 08-05-2010 |
| 20100221034 | CLEANING DEVICE AND IMAGE FORMING APPARATUS - A cleaning device includes: a first scraping member that scrapes off a developer on a surface of a moving body that circularly moves; a second scraping member that is disposed downstream from the first scraping member in a moving direction of the moving body, and that scrapes off residuals remaining on the surface of the moving body; a container having: a first housing portion that houses the developer scraped off by the first scraping member, as a recovered material; and a second housing portion that houses the residuals scraped off by the second scraping member; a discharge port that is disposed in the first housing portion, wherein the developer in the first housing portion is discharged to an outside of the container through the discharge port; and a conveying member that conveys the recovered material housed in the first housing portion to the discharge port. | 09-02-2010 |
| 20100247168 | IMAGE FORMING APPARATUS - An image forming apparatus includes: an image carrier having an endless circumferential surface on which a latent image is formed due to an electrostatic potential difference; a developing device that attaches a toner to the image carrier to form a toner image; an endless intermediate transfer belt that is entrained around a plurality of roll members and moves circumferentially, and contacts the image carrier to transfer the toner image to the intermediate transfer belt; a transferring device that further transfers the toner image that has been transferred to the intermediate transfer belt, to a recording sheet; and a load applying member that cooperates with one of the roll members placed inside the intermediate transfer belt, to nip the intermediate transfer belt to apply a load to the intermediate transfer belt, the load applying member contacting a non-image region of the intermediate transfer belt. | 09-30-2010 |
| 20110013923 | IMAGE FORMING APPARATUS WITH AN INTERMEDIATE TRANSFER MEMBER AND A PLURALITY OF CLEANING MEMBERS - An image forming apparatus includes: an image forming device; an intermediate transfer member; a secondary transferring device; a first cleaning member; a second cleaning member; a contacting/separating device; a release-agent applying device; and a controlling unit. | 01-20-2011 |
