    摘要: A fixing apparatus has a heater that includes a magnetic shunt alloy whose Curie temperature is set higher than a fixing temperature; an induction heater that generates an alternating magnetic field applied to the magnetic shunt alloy and performs electromagnetic-induction heating on the heater; and a body controller that controls the induction heater so as to adjust the fixing temperature in each fixing job. The body controller controls the induction heater so as to perform electromagnetic-induction heating on the heater, during a period between fixing jobs. The body controller thereby reduces a temperature difference generated on the heater between portions corresponding to paper feeding and non-paper feeding areas in a previously executed fixing job.

    摘要: A fixing apparatus can prevent an excessive rise in temperature of a paper non-passage area due to diverted flow of magnetic flux from a paper passage area of a heat-producing element to a paper non-passage area thereof has a small configuration. A center core is rotated by a rotation section, bringing cutaway parts to a magnetic path masking position, and the degree of magnetic coupling between the center core and a heat-producing roller is weakened, suppressing an excessive rise in temperature of paper non-passage areas of the heat-producing roller. With this fixing apparatus, switching of the intensity of magnetic coupling between the center core and heat-producing roller can be performed simply by rotating the center core. Also, with this fixing apparatus, it is not necessary for magnetism suppressing elements to be provided as separate members, enabling the configuration to be made simpler and less expensive.

This apparatus has a top-surface paper ejection unit (130) that ejects paper P on which an image has been formed by an image forming unit (110) onto the top surface of the apparatus body (101); a top-surface paper ejection tray (150) that can be opened and closed with respect to the apparatus body (101) and receives paper P ejected by the top-surface paper ejection unit (130); an object placement platform (160) whose object placement surface (161), on which an object is placed, is exposed by opening the top-surface paper ejection tray (150); and a two-dimensional sensor (170) for imaging an object placed on the object placement platform (160). The apparatus has a configuration in which the top-surface paper ejection tray (150), when open, serves as a support for the imaging section. In this image forming apparatus (100), the top-surface paper ejection tray (150) also functions as a support for the two-dimensional sensor (170).
