摘要： A transfer device includes a transfer belt, a transfer roller and a tension roller over which the transfer belt is passed in a tensioned condition and which is made to be in an electrically floated state; it also includes a guide member that is installed in the vicinity of the tension roller. A control section, in transfer processing, controls a first switch so that the guide member is in a grounded state while controlling a second switch so that an electric current being caused to flow to the transfer roller becomes a first electric current; and in cleaning processing, controls the first switch so that the guide member is in an electrically floated state while controlling the second switch so that an electric current being caused to flow to the transfer roller becomes a second electric current.

摘要： A secondary transfer unit stretches a transfer belt in an endless form over a driving roller, a driven roller, a transfer roller, an auxiliary roller, and a support roller therebetween. The transfer belt moves, by rotation of the driving roller, along a circulation path which passes through a transfer position. The transfer roller and the auxiliary roller press the transfer belt from the inner peripheral surface of the transfer belt toward an intermediate transfer belt in the transfer position. The transfer belt has an outer peripheral surface thereof which is pressed against the intermediate transfer belt and is roughened so that the surface roughness of the outer peripheral surface becomes 6 μm to 10 μm.

摘要： A transfer device includes a plurality of primary transfer rollers, a second link member and a regulatory member. The regulatory member restrains the second link member from moving further than a predetermined position toward the second direction. The second link member causes the primary transfer rollers to be displaced as it moves. The second link member is split into a plurality of link arms of which overall length is variable within a predetermined range; and its joint portion includes an elastic member urging the plurality of link arms toward a direction to which the overall length gets longer in a state where the second link member is most separate from a cam shaft, and a first locking section and a second locking section engaging the plurality of link arms with one another for the overall length not to get longer beyond a maximum value.

摘要： A belt carrying device includes supporting rollers, an endless belt supported by the supporting rollers, and guiding members provided on the endless belt. The endless belt is rotated by rotation of the supporting rollers. An outer peripheral surface of the endless belt is in contact with a cleaning member. The guiding members are provided on those projecting areas of the endless belt, which project in an axial direction of the supporting rollers from both end surfaces of the supporting roller. A guiding member suppresses meandering of the endless belt by coming into contact with an end surface of the supporting roller. Formed on the end, surfaces of at least one of the supporting rollers are projecting sections and groove sections, which are rotated around a rotation axis of the at least one of the supporting rollers in response to rotation of the at least one of the supporting rollers.

摘要： An image forming apparatus includes a waste toner box, a base, a detection sensor, a counter and a controller. The waste toner box collects toner not transferred to a sheet but remaining on a surface of a photoreceptor. The base is for placing the waste toner box thereon, and a position of the base changes with a weight of the waste toner box placed thereon. The detection sensor detects the position of the base to detect an amount of toner in the waste toner box placed on the base. The counter counts the number of sheets with images formed thereon. The controller determines whether or not to continue image formation on a sheet on a basis of a signal from the detection sensor and the counter.

摘要： An image forming apparatus is provided with an image bearing unit, an intermediate transfer unit, a primary transfer unit, a pre-transfer charger, and a control portion. The pre-transfer charger is located downstream of the primary transfer unit and upstream of the secondary transfer unit in a revolving direction, faces the outer peripheral surface of the intermediate transfer unit along a perpendicular direction perpendicular to the revolving direction, and charges the intermediate transfer unit when voltage is applied. The control portion, at time when determination is made as to the necessity of cleaning the pre-transfer charger, secondarily transfers a cleaning assessment toner image by switching between a state in which the voltage is applied to the pre-transfer charger and a state in which the voltage is not applied to the pre-transfer charger, the cleaning assessment toner image being in a uniform density.
