20080226334 | DISCHARGER, IMAGE CARRIER UNIT, AND IMAGE FORMING APPARATUS - A discharger includes: a discharge electrode member that is placed opposedly to a member to be charged; an opposed electrode member that is placed opposedly to the discharge electrode member; and a power source circuit that applies a discharge voltage for generating a discharge between the discharge electrode member and the opposed electrode member, and the electrode member having a surface that includes a covered layer covered by a covering material is formed on a surface opposed thereto, and the covering material containing a carbon atom, or a carbon atom and another atom or other plural atoms as a main component, and having an SP3 structure by a carbon atom. | 09-18-2008 |
20100080579 | IMAGE FORMING APPARATUS AND APPARATUS - The image forming apparatus includes: an image forming section forming an image on a recording medium; an attachable and detachable storing container storing waste powder discarded and transported from the image forming section; a transport path for transporting the waste powder; a first discharging part allowed to be shut off and discharging the waste powder to an outside of the transport path; a second discharging part provided downstream of the first discharging part in a transporting direction and discharging the waste powder to the storing container; a powder storage part storing the waste powder when the storing container is removed; and a controller causing the shut first discharging part to be opened when the storing container is removed, and causing the waste powder to be discharged from the first discharging part. The powder storage part has capacity enough for storing the waste powder when the first discharging part is opened. | 04-01-2010 |
20100080580 | IMAGE FORMING APPARATUS - The image forming apparatus includes: an image forming section forming an image on a recording medium; first and second storing containers attachably and detachably provided and storing waste powder discarded from the image forming section; a first discharging part allowed to be shut off and discharging the waste powder to the first storing container; a second discharging part discharging the waste powder to the second storing container; a first transporting section transporting the waste powder to the first discharging part; a second transporting section transporting, toward the second discharging part, the waste powder transported to the first discharging part, when the first discharging part is shut off; and a controller shutting off the first discharging part and stopping the first transporting section or reducing an output of the first transporting section, when the first storing container is removed in a state where the first discharging part is opened. | 04-01-2010 |
20100080637 | IMAGE FORMING APPARATUS AND WASTE POWDER TRANSPORTING METHOD - An image forming apparatus includes: an image forming section including first and second image forming parts each forming a toner image by using an image forming unit to be mounted, the first and the second image forming parts being inhibited from forming respective toner images if an image forming unit is not mounted to the first image forming part, the first image forming part being allowed to form a toner image if an image forming unit is mounted to the first image forming part while an image forming unit is not mounted to the second image forming part; and a transporting section including first and second receiving parts receiving waste powder discarded by the first and second image forming parts, respectively, and that transports the received waste powder. The second receiving part is provided downstream of the first receiving part in a transporting direction of the waste powder. | 04-01-2010 |
20100080638 | IMAGE FORMING APPARATUS, POWDER TRANSPORTING APPARATUS AND WASTE-POWDER TRANSPORTING METHOD - An image forming apparatus includes: an image forming section forming an image on a recording medium; first and second storage parts storing waste powder discarded from the image forming section; a transport path of the waste powder; first and second discharging parts provided on the transport path and discharging the waste powder to the first and second storage parts, respectively; a transporting section provided along the transport path between both discharging parts, and transporting the waste powder toward the second and first discharging parts in first and second operating states, respectively; a feeding section feeding the waste powder from the image forming section to the transport path between both discharging parts; and a controller making the transporting section operate in both operating states, and stopping the feeding section or reducing its output when switching a transporting direction of the waste powder by switching from the first to second operating state. | 04-01-2010 |
