20100166468 | IMAGE FORMING APPARATUS - An image forming apparatus includes a first image carrying member for carrying a first toner image; a second image carrying member for carrying a second toner image in a maximum amount, of the second toner image carried on the second image carrying member, larger than a maximum amount of the first image carried on the first image carrying member; a first transfer member for electrostatically transferring the first toner image onto a transfer medium in a first transfer nip formed by bringing the transfer medium into contact with the first, image bearing member; and a second transfer member for electrostatically transferring the second toner image onto the transfer medium in a second transfer nip formed by bringing the transfer medium into contact with the second bearing member so that a length of the second transfer nip with respect to a movement direction of the transfer member is longer than a length of the first transfer nip with respect to the movement direction. | 07-01-2010 |
20100215412 | TRANSFER APPARATUS, IMAGE FORMING APPARATUS, AND IMAGE FORMING METHOD - A transfer apparatus includes an image bearing unit, a transfer member and a bias generator. The image bearing unit is configured and arranged to bear an image. The transfer member is arranged with respect to the image bearing unit to form a nip portion therebetween. The transfer member includes a substrate and an elastic member. The substrate has a recessed portion with an opening width of the recessed portion being larger than a width of the nip portion as measured in a moving direction of the transfer member. The elastic member is fixed in the recessed portion and wound around the substrate. The elastic member has a volume resistivity of 1×10 | 08-26-2010 |
20100278567 | Image Forming Apparatus - An image forming apparatus includes an image bearing member for bearing a toner image; a rotatable intermediary transfer member; and a transfer unit, configured and positioned to form a transfer nip between the intermediary transfer member and the image bearing member, for transferring the toner image from the image bearing member onto a surface of the intermediary transfer member. The transfer unit includes a sheet member on which the intermediary transfer member is slidable, and includes an elastic member for urging the sheet member toward the intermediary transfer member at a position of the transfer nip. The sheet member is provided with a reinforcing portion, having a linear expansion coefficient different from that of the sheet member, in an area in which the elastic member urges the sheet member. | 11-04-2010 |
20110194879 | IMAGE FORMING APPARATUS - An image forming apparatus includes an image bearing member for bearing a toner image; a movable endless transfer belt for transferring the toner image from the image bearing member onto a transfer material; and a transfer device for transferring the toner image from the image bearing member toward the transfer belt. The transfer device includes a transfer member for sliding on an inner surface of the transfer belt in contact with the inner surface, a supporting member for supporting the transfer member and an urging member for urging the supporting member toward the transfer belt. The transfer member is contacted to the inner surface of the transfer belt at a contact surface thereof without rotation relative to the supporting member during movement of the transfer belt. The supporting member is rotatable about a center axis thereof so as to be moved in a direction perpendicular to a movement direction of the transfer belt. The contact surface is convex with predetermined curvature toward the transfer belt. | 08-11-2011 |
20120213561 | LIMITED OZONE GENERATOR TRANSFER DEVICE - A limited ozone generator transfer device includes a ceramic substrate having conducting lines, a dielectric layer, and a top conducting layer with slots therein that align with the underlying conducting lines. Corona is generated in the slots by applying an AC voltage of about 2.5 kVp-p across the electrodes. This device is “green” in that it generates significantly less ozone than conventional transfer devices, thus reducing requirements on an ozone collection system. | 08-23-2012 |
20130223901 | IMAGE FORMING APPARATUS WITH TRANSFER NIP ADJUSTMENT FUNCTION - A secondary transfer facing roller includes a roller part that has a through-hole penetrating in a rotary shaft line direction at a rotation center position, and a penetrating shaft member penetrating the through-hole of the roller part and spinning the roller part on a surface of the penetrating shaft member. Eccentric cams are fixed to both end regions that are not located in the roller part, so as to rotate integrally with the penetrating shaft member. A position regulating cam and an abutting roller form a gap between the intermediate transfer belt and the secondary transfer roller immediately before a transfer sheet enters a transfer nip part. While the gap is formed, current flows between the intermediate transfer belt and the secondary transfer roller via the position regulating cam and the abutting roller. | 08-29-2013 |
20140270862 | IMAGE-FORMING APPARATUS - An object of the invention is to cause a transfer device to make more stable contact with a belt, thus yielding preferable transfer performance. In an image-forming apparatus | 09-18-2014 |
20150117913 | Transfer System for an Electrophotographic Device - A device for transferring images from an image donating member to an image receiving medium comprises a substrate, at least two electrodes disposed on the substrate, and at least one layer of coating disposed on the substrate having an outer surface for forming a nip region with the image donating member. The at least two electrodes are controllable to produce an electric field and control a position thereof at the nip region to allow transfer of an image from the image donating member to the image receiving medium in an image transfer operation. | 04-30-2015 |
