    摘要： In a fixing apparatus using an induction heating type of heating apparatus, there are provided an excitation apparatus that generates magnetic flux, an opposed core located opposite the excitation apparatus, a fixing belt that is induction-heated by the aforementioned magnetic flux, and magnetism masking elements that block magnetic paths corresponding to paper non-passage areas of fixing belt between the excitation apparatus and the opposed core. By blocking magnetic paths between the excitation apparatus and the opposed core by the magnetism masking elements, magnetic flux that induction-heats the fixing belt is effectively masked, and an excessive rise in temperature of paper non-passage areas of fixing belt is prevented.

    摘要： A color image forming apparatus capable of reducing the total printing time and having an excellent cost performance. In the four developments and primary transfer by the toner of yellow, magenta, cyan, and black for forming one sheet of color image, the development and primary transfer of the toner of the last color, black, is performed at a different speed from that of the toner of the other colors. Furthermore, the secondary transfer and fixation are performed at the same speed as of the development and primary transfer of the toner of the last color, black.

    摘要： An image forming apparatus with three-dimensional object imaging capability is provided that is compact, has a small footprint, and is easy to use. 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).

    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.
