摘要： A timer clocks and accumulates time periods during each of which a recording sheet is transported or transfer bias is applied as transfer execution periods. When the accumulated value reaches a predetermined value, the timer outputs a time-up signal to a CPU and then clears the accumulated value. The CPU executes a cleaning operation at the time the time-up signal is inputted from the timer. In the cleaning operation, the CPU causes a high-voltage power source to apply cleaning bias to a transfer electrode roller while causing a high-voltage power source to apply delivery bias to an auxiliary cleaning roller, in order to return toner attracted to the auxiliary cleaning roller to a photosensitive drum via a transfer belt.

摘要： A junction/disjunction unit of a multicolored image forming apparatus joints/disjoints a transfer material holder with/from an image holder, to switch over between a monochromatic image forming mode which uses a specific image forming unit and a multicolored image forming mode which uses a plurality of image forming units. For switching the image forming mode, a driving unit for driving the junction/disjunction unit also drives an auger provided for conveying toner, which has been recovered by a transfer material holder cleaning unit for recovering toner remaining on the transfer material holder, into a recovery container. Accordingly, a driving force outputted from the driving unit can be effectively utilized, and thereby good cost performance can be realized.

摘要： A belt conveyor member includes an endless belt and a cleaning blade. The cleaning blade is configured to remove residual toner remaining on a surface of the endless belt which is processed into a smooth surface. The endless belt has a first region and a second region. The first region is a region in contact with the cleaning blade which is located outside a region for a recording sheet of a maximum usable width to pass therethrough. The second region is located outside the first region. A contact surface between the cleaning blade and the first region is in a rough condition free from intimate contact.
