<p>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. <IMAGE></p> |
