    IPC: G03G15/20

    Abstract: A heating device includes a heating roller having a resistance heat-generating layer that generates heat by passage of a current through the resistance heat-generating layer, a support member that supports a treatment portion in which a heating treatment is performed, a belt that is stretched between at least the heating roller and the support member and that rotates, and a pressure rotating body that rotates in such a manner as to press a sheet-shaped heating target that is an object to be subjected to a heating treatment against the treatment portion including an outer peripheral surface portion of the belt that is supported by the support member and in such a manner as to cause the heating target to pass through the treatment portion. The heating roller is not equipped with a power receiving component configured to receive a rotational power that is transmitted.

    IPC: G03G15/20

    CPC classification number: G03G15/2017

    Abstract: A fixing device includes a fixing member that has an outer peripheral surface and an inner peripheral surface, is rotatably provided, comes into contact with, of a recording material on which an image is formed, a surface on which the image is formed, and fixes the image to the recording material, a rotating member that is rotatably provided and includes, at an outer peripheral portion, a contact surface coming into contact with the inner peripheral surface of the fixing member, and a removing member that is disposed to be in contact with the outer peripheral surface of the fixing member, is rotatably provided, and removes an attached object attached to the outer peripheral surface using a rotation speed difference with respect to the fixing member.

    Abstract: A fixing device includes an endless belt, a fixing member that presses the belt against a recording medium holding an unfixed image to fix the unfixed image onto the recording medium, a restorer that is pressed against a surface of the belt after the image is fixed to restore the surface of the belt to a state before a fixing operation, and a changer that changes a pressing load of the restorer in accordance with a difference in a state of the surface of the belt between before the fixing operation and after the fixing operation.
