    摘要： An image forming apparatus comprising a rotatable image bearing member (7), a toner image formation means (Pa,Pb,Pc,Pd) for forming a toner image on said image bearing member (7), a transfer member (14), contactable to said image bearing member (7), for transferring a toner image from said image bearing member (7) onto a recording material (S) in a transfer region (N2), a voltage source (16) for applying a first bias voltage to said transfer member (14) when said transfer member transfers the toner image onto the recording material (S). Said image forming apparatus avoids defects due to substances bleeding from transferring member by transferring a toner image onto a transfer member (14) in absence of recording material (S) in said transfer region (N2), the second bias voltage used during this transfer is smaller than the first bias voltage. The toner image is back-transferred to the image bearing member by using a transfer bias of opposite polarity compared to the first or second bias voltage.

    摘要： A predetermined level of voltage is applied to a transfer roller (26) to transfer a toner image on a photosensitive drum (22). After a predetermined number of recording sheets are made, a cleaning sequence is started wherein a voltage of -900V is applied as a cleaning voltage. Before applying the transfer voltage of 3kV, intermediate voltage is applied once or more under the control of a control unit (30). The control unit (30) instructs the application of the voltage through an electrical circuit (32) to the transfer roller (26) based on conditions set in a memory (33) and/or information given by a machine temperature sensor (35).

    摘要： It is an object of the invention to prevent reduction in output speed in the case where toner or the like adhered to a transfer belt is transferred to a side of an image carrying body and cleaning is performed by a cleaning device on a side of the image carrying body. A toner image transfer apparatus (6) is constituted by extending a transfer belt (63) between a first transfer roller (61), which is brought into pressure contact with a photoreceptor (2), and a second transfer roller (62) disposed away from the photoreceptor and on a downstream side in a sheet conveying direction, and a circumferential length of the transfer belt (63) is set to be equal to or less than a spacing between sheets conveyed (sheet spacing D) such that, in the sheet spacing D, over which a sheet passes a transfer position and which a subsequent sheet reaches, a cleaning voltage is supplied to shift toner or the like, adhered to the transfer belt (63), to the photoreceptor (2) to have the same removed by a cleaning device (7) on a side of the photoreceptor (2). An entire circumference of the transfer belt (63) enables using the sheet spacing D to perform cleaning, thus ensuring a favorable cleaning quality without reduction in output speed.

    摘要： When a cleaner is included exclusively for cleaning a transfer/transport belt to remove toner therefrom, the structure of an image forming apparatus becomes complex and the costs thereof increase. The present invention attempts to remedy this situation. Specifically, a difference between a peripheral speed relative to the transfer/transport belt to be set for cleaning and a peripheral speed relative to photosensitive drums to be set therefor is made larger than that between peripheral speeds to be set for ordinary image formation. Because of this constituent feature, unnecessary toner on the transfer/transport belt is efficiently transferred onto the photosensitive drums on a stable basis for a short period of time.
