  • Publication number: 20200183309
    Abstract: A fixing device according to an embodiment includes a fixing belt, a pressurizing roller, a supporting member and a heating member. The fixing belt is supported to be capable of circularly moving and is formed endless. The pressurizing roller comes into contact with an outer circumferential surface of the fixing belt and forms a nip for holding a sheet. The supporting member is disposed on an inner side of the fixing belt and extends in an axial direction of the fixing belt. The heating member is disposed on the inner side of the fixing belt and supported by the supporting member and extends in the axial direction of the fixing belt. If the pressurizing roller does not pressurize the fixing belt, end portions of a second principal plane opposite to a first principal plane on the pressurizing roller side of the heating member are separated from the supporting member.

  • Patent number: 10209652
    Abstract: An image forming apparatus comprises a transfer section, a fixing section, and a controller. The transfer section includes a transfer rotating body for conveying a sheet at a first linear velocity, and transfers a toner image onto the sheet. The fixing section forms a nip sandwiching the sheet with a first rotating body and a second rotating body, and a heating section for heating the sheet onto which the toner image is transferred. The controller executes a sheet acceleration and deceleration control for setting a linear velocity of the first rotating body to a second linear velocity from the first linear velocity before the tip of the sheet reaches the nip, and decelerating the linear velocity of the first rotating body from the second linear velocity to the first linear velocity at the time the tip of the sheet reaches a predetermined range in a sheet conveyance path.
