    摘要: An image forming apparatus includes a control unit for executing a control operation in which the photoreceptor drum is not to directly contacted with a divided holding region surface on the transfer belt onto which a transfer sheet fed again by the trayless device is held. In the control operation, the two-sided image formation is previously conducted on the transfer sheets, the number of which corresponds to the surplus number (2) obtained when the number (7) of transfer sheets of continuous two-sided image formation is divided by the number (5) of the divided holding regions (panels) on the transfer belt passing through a transfer position on the photoreceptor drum in a period of time from when a transfer sheet, onto the first image surface of which an image is formed, is held on the transfer belt to when the transfer sheet is fed again to the transfer belt via a transfer sheet conveyance passage of the trayless mechanism, and then the two-sided image formation is conducted on the residual number (7-2=5) of transfer sheets.

    摘要: An image forming apparatus capable of preventing a transfer material detecting unit from making any detection error when the surface of a transfer drum becomes opaque, and restraining transfer film replacement intervals from being shortened with a simple constitution. The image forming apparatus is provided with a transfer material detecting unit for detecting conditions in which a transfer material is conveyed on a transfer material carrier, and a transfer material peeling unit for peeling the transfer material off the transfer material carrier by contacting the surface of the transfer material carrier. At least part of the transfer material peeling unit is disposed so that it at least linearly contacts the axial surface of the transfer material carrier at the same position as that of the transfer material detecting unit in the axial direction of the transfer material carrier.

    摘要: A compact, inexpensive paper detack device has a detack claw mounted to the bottom of a cleaning assembly has a rotatably mounted shaft supporting the detack claw, a pair of shaft support members extending downward from the cleaning housing each having a recess in its lower corner adjacent the imaging member for supporting the shaft and at least one elastic support member extending downward from the cleaning assembly in cooperative association with the pair of shaft support members pressing the shaft into the recess. The elastic support member has a tip bent forward toward the shaft forming a bearing space between the recess and the tip smaller than the diameter of the shaft to provide a snap fit for the shaft on insertion into the bearing between the recess and the elastic support member. The detack claw has an elastomeric tip and the angle between the bottom of the claw and the tangent at the contact point between the detack claw and the drum is between 120.degree. and about 140.degree.. The detack claw is attached to an axially slidable member rotatably mounted to the shaft having a groove therein for removing foreign matter entering the space between the shaft and the axially slidable member.

    摘要: An image density controlling device for an image formation apparatus includes a plurality of image formation devices. A plurality of transfer members carry an image formed by at least one of the plurality of image formation devices. A belt rotates synchronously with the operation of the image formation devices and carries the transfer members. The belt includes a plurality of transfer member carrying areas on which the plurality of the transfer members are respectively carried, and a plurality of non-carrying areas therebetween. A density detection toner image is formed in the non-carrying area by utilizing at least one of the plurality of image formation devices. The density of the density detection toner image is determined to output a density detection signal. The densities of the images transferred to the transfer members are then controlled in accordance with the density detection signal. The density detection toner image formed in each rotation cycle of the belt is cleaned off and formed again at a different position of the belt.

    摘要: A jam processing device comprising a plurality of paper jam detectors positioned in a paper conveying path, a device for forcedly ejecting the jammed paper and a device for selectively controlling actuation of respective components in an image forming apparatus. The jam processing device is suitable for use in an image forming apparatus that holds a sheet of paper on a transfer belt and transfers toner images from a plurality of photosensitive drums to the paper. When a paper jam is developed in the paper conveying path, a mode for forcedly ejecting the paper is initiated to charge and destaticize the transfer belt. Further, the paper is fed and ejected from the paper conveying path while each photosensitive drum is being charged and destaticized.
