  • Publication number: 20160223958
    Abstract: An image forming apparatus includes: an image forming portion configured to form a toner image on a recording material with a first toner and a second toner which are different in color from each other; and a light irradiating portion configured to irradiate, with light, the toner image formed on the recording material by the image forming portion. The first toner and the second toner include resin materials containing a common functional group. An infrared absorption wavelength range resulting from the functional group is 2.6 ?m or more and 3.6 ?m or less. A maximum intensity wavelength of the light with which the toner image is irradiated by the irradiating portion is in the 2.6 ?m or more and 3.6 ?m or less.

  • Patent number: 9116482
    Abstract: A heating member has a multi-layered structure of n layers in total to which layer numbers are assigned sequentially from one on a heat source side to a surface in contact with a recording medium. An n?th layer is heated by the heat source. The thermal permeability of the n?th layer is larger than the thermal permeability of a n?1?th layer and satisfies the following relationship: ?{square root over (?nt)}?dn where, ?n[m2/s] is the thermal diffusivity of the n?th layer, and dn[m] is the thickness of the n?th layer.

  • Patent number: 7614716
    Abstract: A method of discriminating a type of recording medium and a discriminating apparatus in which the type of recording medium is discriminated based on a temperature change of the recording medium when the recording medium is heated. A type of recording medium is discriminated based on a phase difference between a pulse signal input to a heating device and a pulse signal output by a detecting device detecting a temperature of a recording medium.
