399318000 | By pressure | 6 |
20080219720 | Image forming apparatus - A moving unit is made to perform a contacting operation at least two times. The contacting operation includes relatively moving an endless belt and an image carrier so that the endless belt and the image carrier to come in contact with each other. | 09-11-2008 |
20080253813 | IMAGE FORMING APPARATUS WITH TRANSFER MEMBER FOR TRANSFERRING TONER ON IMAGE BEARING MEMBER - Deflection recessed in a bow shape at the axial central portion in the longitudinal direction of the transfer member is avoided to prevent failure in image caused by the transfer nip being improperly forming at the central portion. The pressing force of the transfer member against an image bearing member resulting in failure in transfer is made uniform in the longitudinal direction. The transfer member forming the transfer nip are pressed toward the photosensitive drum at the central portion in the longitudinal direction or in the positions which are spaced apart toward the center from the ends to avoid the deflection of the transfer member. | 10-16-2008 |
20080317521 | TRANSFER BELT DEVICE, METHOD OF ASSEMBLING THE SAME, AND IMAGE FORMING APPARATUS - Rollers including a tension roller are arranged in parallel. A pair of supporting members supports both ends of the rollers. A transfer belt is supported by the rollers. A biasing member applies a tension to the transfer belt by biasing the tension roller in a predetermined direction. The tension roller is movably supported in a straight-line direction. The biasing member is arranged in an area surrounded by the supporting members and the transfer belt in a direction of traversing from one supporting member to other supporting member. | 12-25-2008 |
20110286774 | IMAGE-FORMING DEVICE AND IMAGE-FORMING METHOD - An image-forming device includes an image carrier belt, a roller, a transfer material transporting member, and a transfer roller. The image carrier belt carries an image. The transfer material transporting member transports a transfer material. The transfer roller transfers the image to the transfer material at a nip. The transfer roller includes a concaved portion formed on a peripheral surface thereof and a transfer material gripping portion that grips the transfer material in the concaved portion. The transfer roller is in contact with the roller via the image carrier belt. A first interaxial distance between a rotation axis of the transfer roller and a rotation axis of the roller as the transfer material is gripped is larger than a second interaxial distance between the rotation axis of the transfer roller and the rotation axis of the roller as the image is being transferred onto the transfer material at the nip. | 11-24-2011 |
20120039641 | IMAGE FORMING APPARATUS WITH TRANSFER MEMBER FOR TRANSFERRING TONER ON IMAGE BEARING MEMBER - Deflection recessed in a bow shape at the axial central portion in the longitudinal direction of the transfer member is avoided to prevent failure in image caused by the transfer nip being improperly forming at the central portion. The pressing force of the transfer member against an image bearing member resulting in failure in transfer is made uniform in the longitudinal direction. The transfer member forming the transfer nip are pressed toward the photosensitive drum at the central portion in the longitudinal direction or in the positions which are spaced apart toward the center from the ends to avoid the deflection of the transfer member. | 02-16-2012 |
20130164053 | IMAGE FORMING METHOD AND IMAGE FORMING APPARATUS - The image forming method comprising: forming a toner image on an image carrier; transferring the toner image formed on the image carrier onto a recording medium; and transforming the toner image on the image carrier into a semi-film by applying a pressure. And the image forming apparatus comprising: an image carrier; a toner image forming unit configured to form a toner image on the image carrier; a transfer unit configured to transfer the toner image formed on the image carrier onto a recording medium; and a toner image transforming unit configured to transfer the toner image on the image carrier into a semi-film by applying a pressure to the toner image. | 06-27-2013 |
