An image forming apparatus includes a curved conveyance path being formed by an outer guide and an inner guide, and a control unit configured to control a first conveyance unit disposed on upstream of the conveyance path and a second conveyance unit disposed on downstream of the conveyance path such that a conveyance speed of the first conveyance unit is set greater than a conveyance speed of the second conveyance unit, in a case where an image surface of the recording material on which an image is formed faces the inner guide, and perform control of the first and the second conveyance units in such a manner that the conveyance speed of the first conveyance unit is set less than the conveyance speed of the second conveyance unit, in a case where the image surface of the recording material on which the image is formed faces the outer guide.

Image forming apparatus for forming an image on a recording material

A glossing apparatus for glossing at least part of a toner image on a recording material includes a film, a supply roller on which the film is wound, a wind-up roller configured to wind-up the film, and a driving device configured to drive the wind-up roller to rotate. In addition, a heating device heats at least part of the toner image on the recording material through the film at a heating position between the supply roller and the wind-up roller in a heating operation, a reversing device reverses the film to the supply roller to use an unused area of the film not having been contacted to the recording material during the heating operation, and a conveying device conveys the recording material toward the heating position so that the toner image on the recording material is heated using the unused area of the film.

Surface treatment apparatus having reusable film

A sheet conveyance apparatus includes a sheet conveyance unit configured to convey a sheet, a transfer unit disposed downstream of the sheet conveyance unit and configured to transfer a toner image onto the sheet, a shifting unit configured to shift the sheet conveyed by the sheet conveyance unit in a width direction by shifting the sheet conveyance unit, a detection unit configured to detect a position of the sheet in the width direction while the sheet is being conveyed by the transfer unit, and a control unit configured to control the shifting unit. The control unit causes the sheet conveyed by the sheet conveyance unit to shift in the width direction based on a result detected by the detection unit while the sheet is being conveyed by the transfer unit.

Sheet conveyance apparatus and image forming apparatus

An image forming apparatus includes a heat source, a toner containing member containing toner, and an electric fan for generating air flow in an air flow path formed between the heat source and the toner containing member. In the image forming apparatus, a temperature of the heat source reaches a glass transition point of the toner. After the electric fan is changed from a driving state to a rest state, a phase transition member for absorbing heat is disposed in a heat transfer path, in which heat transfers, from the heat source to the toner containing member.
