摘要： A transfer device includes a plurality of photoconductors, a belt, a plurality of primary transfer rollers and control circuitry. The plurality of primary transfer rollers is disposed for the plurality of photoconductors, respectively. The plurality of primary transfer rollers brings the belt into contact with or separate the belt from the plurality of photoconductors. The control circuitry causes at least one of the plurality of primary transfer rollers to press against a corresponding at least one of the plurality of photoconductors to shift a printing mode.

摘要： An image forming apparatus includes a plurality of image bearers, a plurality of rotation reference position detectors, and circuitry. Each of the plurality of rotation reference position detectors faces a corresponding image bearer of the plurality of image bearers to detect a rotation reference position of the corresponding image bearer. The circuitry performs, before an operation of rotating the plurality of image bearers, alignment control based on a result of detection performed by the plurality of rotation reference position detectors. The alignment control is control of driving of the plurality of image bearers to acquire a given relationship between the respective rotation reference positions of the plurality of image bearers. The circuitry determines whether to perform the alignment control based on whether the operation of rotating the plurality of image bearers is a function maintenance related operation.

摘要： A belt drive apparatus is equipped with an endless belt rotationally movable by being supported by a plurality of rollers. A moving speed signal output part outputs a signal based on a rotational movement of the endless belt. A width direction position signal output part outputs a position signal for which its value changes in response to a position of the endless belt in a direction of width of the endless belt. A width direction position control part controls a position of the endless belt in the direction of width of the endless belt. A process execution part performs a predetermined process using the signal output from the moving speed output part based on the position signal output from the width direction position signal output part.
