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 steam engine and an electric motor are arranged, which respectively drives an air compressor. The compressed air from the air compressor is supplied to a compressed air using device through a common air tank. The steam is supplied to the steam engine through a steam supply path, and the steam used in the steam engine is supplied to a steam using device through a steam exhaust path. The steam pressure is monitored by a pressure sensor arranged in a steam header ahead of the steam exhaust path. The air pressure is monitored by a pressure sensor arranged in an air tank. A steam supply valve is controlled based on the steam pressure and the air pressure, and the electric motor is controlled based on the air pressure. The steam engine is preferentially driven over the electric motor by shifting the target value of the air pressure.
