    摘要: Disclosed is a cylindrical rotary member including a conductive layer; a coil disposed inside the rotary member, the coil including a helical portion having a helical axis that is substantially parallel to a generatrix direction of the rotary member, the coil forming an alternating magnetic field to generate heat in the conductive layer by electromagnetic induction; a core disposed inside the helical portion, the core inducing a line of magnetic force of the alternating magnetic field; a roller coming in contact with an outer surface of the rotary member to form a fixing nip portion; and a metal stay disposed inside the rotary member, in which an image on a recording material is fixed to the recording material by being heated at the fixing nip portion and the stay is disposed outside the coil and has a shape that does not form an electrical loop around the coil.

    摘要: In a fixing device, an alternating current is caused to flow through a coil so as to causes an electrically conductive layer of a rotating member to generate heat, and an unfixed image on a recording medium is heat fixed onto the recording medium by the heat generated by the electrically conductive layer. A frequency range of the alternating current is from 20.5 kHz to 100 kHz. With respect to a generatrix direction of the rotating member, a magnetic member and a spirally shaped portion of the coil have lengths, with which the magnetic member and the spirally shaped portion extend beyond both end portions of the rotating member.

    摘要: A sheet conveyance device includes first, second, and third rotating members and a switching unit. The first rotating member rotates in one direction. The second rotating member conveys a sheet in a first direction with the first rotating member rotating. The third rotating member conveys the sheet in a second direction, different from the first direction, in conjunction with the first rotating member rotating. The switching unit switches from a first state where the second rotating member contacts a sheet first surface and the first rotating member contacts a sheet second surface to a second state in which the first rotating member contacts the first surface of the sheet and the third rotating member contacts the sheet second surface by moving the second rotating member before a trailing edge of the sheet conveyed in the first direction is conveyed by the first rotating member and the second rotating member.

    摘要: Provided is a driving force transmission device including: an actuator (22) that, in a case where one of a first annular gear (11), a second annular gear (14), and a carrier (16) is an input member, another one is an output member, and the remaining one is a rotational member, causes one of the input member and the output member to rotate integrally with the rotational member. When driving force is inputted from the drive source to the input member and input member is rotated unidirectionally, the rotation direction of the output member in the case where one of the input member and the output member rotates integrally with the rotational member is reversed with respect to that in a case where one of the input member and the output member does not rotate integrally with the rotational member.
