Abstract: A fusing device has a heater, a fusing rotary member heated thereby, a pressing rotary member in contact with the fusing rotary member to form a fusing nip, an adjustment mechanism adjusting a fusing pressure to adjust the nip width of the fusing nip, a temperature sensing member, and a control portion. By the control portion, the fusing pressure is set at a first set value during fusing warm-up operation for raising temperature of the fusing rotary member, is set at a third set value when a first sheet of paper after completion of fusing warm-up operation passes through the fusing nip, and is changed to a second set value before sheets of paper for a preset number of pages pass through the fusing nip after completion of fusing warm-up operation. Of the set values, the third is greatest, the second is second greatest, and the first is smallest.

Abstract: In an image forming apparatus, a first motor causes a first rotor to rotate. The first motor rotates based on a first drive signal. A second motor causes a second rotor to rotate. The second motor rotates based on a second drive signal. A reading unit is provided between the first rotor and the second rotor. Based on a read signal, the reading unit reads a paper sheet being conveyed line by line. In a first period, a read signal generation unit generates the read signal in accordance with a frequency of the first drive signal. In a second period, the read signal generation unit generates, as the read signal, a signal for reading the paper sheet being conveyed at a reference speed.

Abstract: An image reading portion includes a light emitting portion and a plurality of photoelectric conversion elements. The light emitting portion emits detection light to a target area extending over a surface of a conveying belt and a pair of off-belt areas outside the conveying belt in a width direction. The image reading portion outputs a plurality of pixel data items. A reference member forms a pair of boundary lines by the difference in reflectance of the detection light at a pair of reference positions in the pair of off-belt areas. A calibration portion identifies data items corresponding to the pair of boundary lines in the plurality of pixel data items obtained by the image reading portion so as to correct reference position data representing a correspondence relationship between the plurality of pixel data items and positions in the width direction.
