    摘要： An image forming apparatus capable of setting a plurality of image forming speeds includes a transfer unit (17) configured to transfer an image formed on an image carrier (13Y, 13M, 13C, or 13K) onto a sheet, a paper feed unit (25) configured to feed the sheet, and a control unit configured to control the conveyance speed of the sheet to accelerate and decelerate without stopping the sheet in a section between the paper feed unit and the transfer unit to synchronize the sheet with the image formed on the image carrier. The control unit (41) changes paper feed timing from the paper feed unit according to the image forming speed if the image forming speed is predetermined.

    摘要： Charge patterns of the images to be printed are produced on a photoconductive strip (OPC) and transformed into toner images using toner, and the toner images are transferred to a transfer strip (TFB) from which they are pressed onto an end image carrier (AT) once the end image carrier has been pivoted onto the transfer strip. The time of the production of the charge pattern on the photoconductive strip (OPC) and/or the transfer of the toner images to the transfer strip (TFB) is set such that the vibrations and disturbances caused on the transfer strip (TFB) and the photoconductive strip (OPC) by the pivoting of the end image carrier (AT) onto or off the transfer strip (TFB) do not have any influence on the production of the charge patterns on the photoconductive strip (OPC) and/or on the transfer of the toner images from the photoconductive strip (OPC) to the transfer strip (TFB).

    摘要： An image forming apparatus includes an image carrier for carrying a toner image, a drive device for driving the image carrier at a predetermined speed, a control device for giving instruction to the drive device to perform predetermined operation, and a transfer device for nipping a recording sheet with a rotary member at the position opposed to the image carrier and for transferring the toner image on the image carrier onto the recording sheet, wherein the control device gives instruction to the drive device to generate a variation having a phase which is reverse to a phase of a variation given to the predetermined speed of the image carrier by a vibration produced at the time of passage of the recording sheet between the image carrier and the transfer device.

    摘要： An image carrier is adapted to support a toner image thereon. A circulating intermediate transfer member is brought into contact with the image carrier to form a primary transfer position at which the toner image is transferred onto the intermediate transfer member. A secondary transfer member is brought into contact with the intermediate transfer member to form a secondary transfer position at which the toner image on the intermediate transfer member is transferred onto a recording medium passing therebetween. A gate roller pair is adapted to nip the recording medium therebetween at a nipping position and to convey the nipped recording medium toward the secondary transfer position. A cleaning blade is retractably brought into contact with the intermediate transfer roller to scrape off toner remaining on the intermediate transfer roller. A conveyance speed of the recording medium at the nipping position is faster than that at the secondary transfer position. The cleaning blade is retracted from the intermediate transfer member until when a trailing end of the recording medium passes through the nipping position, in a case where the recording medium has a stiffness greater than a prescribed level.
