摘要： A belt assembly includes a belt formed into an endless loop, a plurality of support rollers with a rotary shaft, a shaft-end retainer, a movable supporting member, and a drive transmission device. The plurality of support rollers includes a first support roller and a second support roller. The shaft-end retainer is disposed at each end of the rotary shaft of the plurality of support rollers. The movable supporting member supports the first support roller and is movably disposed relative to the shaft-end retainer. The drive transmission device transmits a driving force to one of the plurality of support rollers. The drive transmission device and the movable supporting member are disposed on a same side as the shaft-end retainer in an axial direction of the plurality of support rollers. The drive transmission device is disposed between the shaft-end retainer and the movable supporting member in the axial direction.

摘要： A fixing device includes a fixing belt, a first heater, a second heater, a supporting roller, and a counter roller. During activation of the fixing device, a maximum power is supplied to the first heater, and only the first heater heats the fixing belt. When a temperature on the fixing belt reaches a first reference temperature, the fixing belt is driven rotationally, the power supplied to the first heater is dropped, and power is supplied also to the second heater. When the temperature on the fixing belt reaches a target temperature and the temperature on the counter roller reaches a second reference temperature, fixing operation is allowed to start.

摘要： A belt device for an image forming apparatus, includes an endless belt; a first and second support rollers, each including a rotary shaft, that support the belt with tension; a contacted member that contacts the belt; a shaft displacement device to displace any of the rotary shafts of the support rollers; and a main rotary shaft disposed at a side of the rotary shaft of the first support roller moved by the shaft displacement device along a stretching direction of the stretched surface of the endless belt that the contacted member contacts, relative to a contact portion between the endless belt and the contacted member, and at an opposite side of the contacted member in a direction perpendicular to the stretching direction of the endless belt. As the first support roller and the second roller rotate about the main rotary shaft, the endless belt is separated from the contacted member.

摘要： An image forming apparatus includes a toner image forming device to form a toner image on a rotatable toner image bearer, a looped belt to carry a recording medium, a support roller to rotate the belt, a pressing member to press the belt against the toner image bearer, a transfer electric field generator to form an electric field to transfer the toner image onto the recording medium, and a contact member to contact an end surface of the belt as the belt moves to one side in a belt width direction. The belt includes a first portion pressed against the toner image bearer by the pressing member and a second portion adjoining the first portion. A relative position of the support roller relative to the toner image bearer and the pressing member is determined such that the second portion of the belt contacts the toner image bearer.
