摘要： A fixing device for fixing a toner image on a recording medium includes a heating roller, a fixing roller, an endless fixing belt extended around at least the heating roller and the fixing roller and configured to be heated by the heating roller, a pressing roller disposed opposite to the fixing roller via the fixing belt, a temperature detecting member configured to detect a surface temperature of the heating roller, and a control device configured to control a surface temperature of the fixing belt at a predetermined temperature based on a surface temperature of the heating roller detected by the temperature detecting member. The temperature detecting member contacts a circumferential surface of the heating roller where the fixing belt is not extended around, such that the temperature detecting member is held in a low frictional relation to the circumferential surface of the heating roller.

摘要： A fixing device includes an abutting member arranged at a position between an upstream side of a fixing roller and a downstream side of a heating roller in a moving direction of a fixing belt so as to abut against the fixing belt and expand a fixing region. The fixing device may also include a first supporting member and a second supporting member, which supports the fixing belt, etc., with respect to the first supporting member. An angle, formed between an approaching direction of a sheet-like recording medium and a line tangential to an upstream end of the fixing region in the moving direction of the fixing belt, is set equal to 20° or larger.

摘要： A fixing device includes a fixing belt, a first heater, a second heater, a supporting roller, and a counter roller. During activation of the fixing device, a maximum power is supplied to the first heater, and only the first heater heats the fixing belt. When a temperature on the fixing belt reaches a first reference temperature, the fixing belt is driven rotationally, the power supplied to the first heater is dropped, and power is supplied also to the second heater. When the temperature on the fixing belt reaches a target temperature and the temperature on the counter roller reaches a second reference temperature, fixing operation is allowed to start.

摘要： A fixing device for an image forming apparatus includes a heating member, a pressing member facing the heating member, a coating member for coating a parting agent on the heating member, and agent feeding means intermittently brought into contact with the coating member. Assume that a distance between a nip between the agent feeding means and the coating member, as measured in the direction of forward rotation of the coating member, is A, that a distance between a nip between the coating member and the heating member and a nip between the heating member and the pressing member, as measured in the direction of forward rotation of the heating member, is B, and that the circumferential length of the heating member is C. Then, a period of time T in which the recording medium enters the nip between the heating member and the pressing member satisfies a relation: A+B+C/linear velocity of image formation≦T.
