An image forming apparatus is of a tandem type in which mage forming stations Y, M, C, K for respective colors are arranged along a transfer belt (14). Each image forming station Y, M, C, K has an image carrier (17), a charging means (19) and a developing means (20) which are arranged around the image carrier (17). The image forming apparatus forms a multi-color image by passing the transfer belt (14) through the respective image forming stations. The transfer belt (14) is laid around a driving roller (12) and a driven roller (13) with a constant tension. In one embodiment both the transfer belt and image forming apparatus are located above the exposure means (6,21). Still other embodiment show one or two pivotally movable frame sections (3) containing the transfer belt.

摘要： An image forming apparatus includes a plurality of photosensitive drums, a plurality of developing devices, an intermediate transfer medium, primary transfer members, and a secondary transfer member for transferring toner images onto a transfer material. A full-color mode and a monocolor mode are selectively carried out. The image forming apparatus also includes a CPU for adjusting the length of a non-image forming region, and an intermediate-transfer-medium movement controller. The CPU brings about a switching state in which an image forming region lies between a primary transfer position on the most downstream one of the photosensitive drums and a secondary transfer position and in which non-image forming regions simultaneously lie at the primary transfer position and at the secondary transfer position. The intermediate-transfer-medium movement controller switches between the full-color mode and the monocolor mode during the switching state.

摘要： A toner case includes a case main body, a cover, and a coil spring. The case main body is rotatable and has a toner containing space in which a toner is contained and an opening through which the toner is discharged from the toner containing space. The cover keeps a rotation stop state when the case main body rotates and has a communication space which communicates with the toner containing space via the opening. The coil spring is fixed to the cover so that at least a part of the coil spring is arranged in the communication space. The coil spring vibrates as the case main body rotates.

摘要： A toner pattern is detected by a color misregistration detection sensor to detect a duration of contact between a development roller and a photosensitive drum. A contact/separation motor for driving the development roller is accelerated or decelerated based on the detected duration of contact between the development roller and the photosensitive drum. This control enables shortening the duration of contact between the development roller and the photosensitive drum, thus reducing the shortening of their lifetime.

摘要： An image forming apparatus includes first and second rotatable image bearing members, a rotatable belt member which can abut on the first and second image bearing members, a drive mechanism to attach or separate the second image bearing member to or from the belt member, a rotation drive mechanism, and a controller controlling a rotational speed of the second image beating member so that the second image bearing member rotates with a predetermined circumferential speed difference with respect to the belt member at least when image formation is performed by the second image bearing member. When the second image bearing member abuts on or separates from the belt member, the controller controls the rotational speed of the second image bearing member so that a circumferential speed difference between rotational speeds of the second image bearing member and the belt member is smaller than the predetermined circumferential speed difference.
