摘要： A first control member is disposed in a drum shaft away from a photoconductive drum, and a second control member is disposed in a roller shaft away from a transfer roller. The first and second control members abut on each other at their circumferential surfaces. This helps reduce an amount of displacement resulting from an impact caused by insertion of a recording paper sheet in between the photoconductive drum and the transfer roller, and thereby reduce vibrations in the photoconductive drum. Consequently, a toner image formed on the photoconductive drum and an unfixed toner image transferred onto the recording paper sheet are not affected by vibrations, so that a high-quality image is obtained that is free from blurriness or irregularities.

摘要： An embodiment of a screw conveyor includes a rotating shaft and a conveying blade helically formed around and loosely coupled with the rotating shaft. One or both of two edges of the conveying blade is/are only fixed to the rotating shaft, and a gap is provided between the rotating shaft and the conveying blade. Thereby, the conveying blade can be vibrated in a center axis direction of the rotating shaft by rotation of the rotating shaft and conveyed waste developer.

摘要： An object of the invention is to convey a transfer material properly and securely in a simple structure even where space allowance is limited. An image forming apparatus has a photoconductive body and a transfer device composed of a transfer roller. After a developer image formed on the photoconductive body is electrostatically transferred onto a sheet by the transfer roller, a rear end of the sheet having passed through opposed regions of the transfer roller and the photoconductive body is, by a guiding roller arranged at a downstream side of the opposed portions along a sheet conveying path, guided in conveyance from a non-transferred surface of the transfer material so that it is kept out of contact with the transfer roller.

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： Transfer roller(s) is/are such that either end thereof is formed from fibrous electrically conductive component(s) and such that cylindrical portion(s) in central region(s) is/are, for example, formed from metal roller-like structure(s), either fibrous electrically conductive component outer end being arranged so as to extend somewhat beyond either transfer/transport belt side. Furthermore, outside diameter(s) approximated by tips of respective individual fiber(s) of fibrous electrically conductive component(s) is/are somewhat larger than diameter(s) of metal roller-like structure(s). This makes it possible for electric field(s) to be applied, and for charging to occur, along the full width(s) of transfer/transport belt(s).
摘要翻译： 转印辊的两端由纤维状导电性成分形成，中心区域的圆筒状部分例如由金属辊状物形成 结构，纤维状导电部件外端被布置成稍微延伸到传送带传送带侧。 此外，由纤维状导电部件的各个纤维的尖端近似的外径比金属辊状结构的直径略大。 这使得可以沿着传送/传送带的全部宽度施加电场并且用于充电。
