摘要： A heat-fixing apparatus is provided that enables a rise in temperature of a heating member to be closely tracked, and an excessive rise in temperature of the heating member to be obviated, a simple configuration and irrespective of differences in the operating mode, such as immediately after a rise in temperature or during continuous operation. Different threshold values are set in accordance with different modes, such as a warm-up mode and a fixing operation mode. Threshold decisions on a switching frequency controlled by a frequency control section are made using different threshold values, according to the mode. A switching frequency of switching elements are varied so that power necessary in each mode is supplied to an exciting coil. An excessive rise in temperature is prevented in each mode by halting a switching element drive in accordance with the threshold decision.

摘要： An image heating device includes a heat generating member that heats a body to be heated that is allowed to travel while carrying an image, an excitation unit that is provided close to the heat generating member and generates magnetic flux so as to cause the heat generating member to generate heat by electromagnetic induction, and a heat generation suppressing unit that suppresses an amount of heat generated in the heat generating member by regulating magnetic flux generated by the excitation unit. The heat generation suppressing unit suppresses heat generation of the heat generating member in a region corresponding to a region including at least a center portion of the body to be heated in a width direction. Thus, an amount of heat generated in the width direction can be regulated using a simple configuration at a reduced cost. Further, when the heat generation suppressing unit is operated, diffusion of magnetic flux into a wide area can be prevented.

摘要： A color image forming apparatus having a simple mechanism for switching plural photosensitive drum units and still maintaining a high resolution image is provided. In the apparatus, each image forming unit including each color photosensitive drum is disposed around a rotating shaft of a carriage. Each photosensitive drum has a coupling plate at one end, which is engaged by a drive side coupling plate for transmitting a drive force to the photosensitive drum, when the image forming units is moved to the image forming position. An output shaft that rotates the drive side coupling plate supports an edge of a photosensitive drum shaft in alignment. A toner image formed on the photosensitive drum is transferred onto a transfer belt, which rotates at a constant speed, one by one to form a multicolor image on the transfer belt. The multicolor image on the transfer belt is transferred onto a paper sheet. A transmission between a motor and the carriage include a worm gear.
