Abstract: When a paper dust collecting member is moved in the removal direction, a scraping member scrapes off paper dust adhered to the paper dust collecting member. The paper dust collecting member has a contact member and a holding member. The contact member makes contact with a pair of rollers to collect paper dust. The holding member holds the contact member. The apparatus body has a bottom wall portion. The bottom wall portion is disposed below the paper dust collecting member and extends along the insertion-removal direction to receive the scraped-off paper dust. The paper dust scraped off onto the bottom wall portion is swept out in the insertion direction by the holding member when the paper dust collecting member is inserted.

Abstract: A fixing device includes a heat roller, a heating device, a pressure roller, a conveyance guide, and an air blower. The heating device is disposed inside the heat roller to heat the heat roller. The pressure roller is opposed to the heat roller and forms, together with the heat roller, a nip where a recording medium to be subjected to fixing processing is to be passed through. The conveyance guide guides the recording medium to the nip and is provided with a gap from the pressure roller in a direction in which the conveyance guide guides the recording medium. The air blower is disposed in a region located on the pressure roller side of the conveyance guide in a direction of alignment of the heat roller and the pressure roller and blows air toward the heat roller through the gap between the pressure roller and the conveyance guide.

Abstract: A first temperature sensor detects a first temperature of a region in a heating device. A second temperature sensor detects a second temperature of a portion of the heating device between one end, and an end of the region on the side of the one end. A sheet sensor detects a medium passing a position in a nip region corresponding to a portion of the heating device between the other end, and the other end of the region on the side of the other end of the heating device. A controller starts successive transport of the medium at a first number. Upon deciding that a temperature difference is smaller than a first threshold, and that the medium has not been detected, the controller changes the number of sheets of the successive transport to a second number, fewer than the first number.

The movement control portion controls the movement along the width direction of the pair of conveying members which is nipping the sheet, based on an amount of shift between the position detected by the sensor and a reference position. The detection processing portion detects a sheet size of the sheet. The switching processing portion switches between permitting and not permitting the movement of the pair of conveying members based on a sheet size associated with a sheet feed source and the sheet size detected by the detection processing portion.
