摘要： An image forming apparatus includes a plurality of image forming units that are arranged in parallel so as to be opposed to an intermediate transfer belt or a transfer carriage belt. A black image forming unit that forms a black toner image is arranged at a downstream end or upstream end in the running direction of the intermediate transfer belt or the transfer carriage belt with respect to the other image forming units. The black image forming unit is configured so that its lubricant supplying unit contains a larger amount of lubricant.

摘要： A cleaning device includes a brush roller that removes deposit from a surface of a member to be cleaned by rotating due to a movement of the surface of the member. The brush roller includes a rotary shaft element and a brush provided on the rotary shaft element. The brush abuts the surface of the member due to a weight of the brush roller. The brush includes filaments, and the brush roller satisfies the inequation Y/X≦2.8, where Y is a diameter (denier) of each of the filaments, and X is a length (mm) of each of the filaments.

摘要： An image forming apparatus transfers a toner image from a photoconductive image carrier to a recording medium with a transfer roller and senses the density of a particular toner pattern formed on the image carrier with an optical sensor. A voltage of a first polarity opposite the polarity of the toner is applied to the transfer roller when the toner image is to be transferred to the recording medium. A voltage of a second polarity identical to the polarity of the toner is applied to the transfer roller when the toner pattern is to be moved between the image carrier and the transfer roller. Thus, even when a toner pattern is brought to the transfer roller, the transfer roller is not released from the photoconductive element.

摘要翻译： 图像形成装置将调色剂图像从感光图像载体转印到具有转印辊的记录介质上，并用光学传感器感测形成在图像载体上的特定调色剂图案的浓度。 当将调色剂图像转印到记录介质时，与转印辊的极性相反的第一极性的电压施加到转印辊上。 当调色剂图案在图像载体和转印辊之间移动时，与转印辊的极性相同的第二极性的电压被施加到转印辊上。 因此，即使将调色剂图案带到转印辊上，转印辊也不会从光电导元件释放。

摘要： An image forming apparatus is provided, which includes an image bearing member, a transfer roller having a shaft for transferring an image on the image bearing member to a transfer sheet, a bearing mechanism for supporting the shaft, a discharging device for discharging the transfer, and a joint mechanism which mechanically connects the discharging device with the transfer roller at both ends of the shaft. Both of the transfer roller and the discharging device can be integrally detached from and attached to the image forming apparatus without detaching/attaching the bearing mechanism, by use of a handle. Therefore, an operation for replacing the transfer roller and the discharging device can be performed easily.
