摘要： A fixing device includes an endless, rotatable fixing member, a rotational pressing member, a nip formation member, and an urging unit. The rotational pressing member is rotatably provided in contact with the fixing member. The nip formation member is disposed opposite the rotational pressing member via the fixing member to form a fixing nip between the fixing member and the rotational pressing member. The urging unit is disposed opposite the rotational pressing member via the nip formation member and the fixing member to push against and deform the nip formation member to change a curvature of a contact face between the fixing member and the rotational pressing member at the fixing nip.

摘要： A fixing device includes an endless flexible fixing member, a supporting member having a pipe shape disposed inside a loop formed by the fixing member to support the fixing member, a pressing member disposed opposite the supporting member via the fixing member, and a nip formation member disposed opposite the pressing member via the fixing member to form a fixing nip between the fixing member and the pressing member. The fixing member contacts an outer circumferential face of the supporting member at a side opposite a side at which the fixing member contacts the nip formation member at the fixing nip. The fixing member has slack portions formed upstream and downstream from the fixing nip in a conveyance direction of a recording medium. The slack portions extend toward the pressing member over the fixing nip without contacting either the supporting member or the pressing member.

摘要： A fixing device includes a hollow, generally cylindrical open-sided stationary heat roll, a flexible fuser belt, a fuser pad, a rotatable pressure member, and a roll shape retainer. The heat roll is configured to heat an outer circumference thereof, and defines an elongated longitudinal side opening in one side thereof. The fuser belt is looped for rotation around the heat roll to transfer heat radially outward from the roll circumference. The fuser pad is held substantially stationary along the roll opening outward from the roll hollow and inward from the loop of the fuser belt. The pressure member is pressed against the fuser pad through the fuser belt to form a fixing nip. The roll shape retainer is disposed on the roll opening to retain the generally cylindrical shape of the heat roll.

摘要： In a fixing device, a metal member is provided inside a fixing belt to heat the fixing belt. A first lubricant is applied between the metal member and the fixing belt at a center portion of the fixing belt in an axial direction of the fixing belt that contacts a recording medium bearing a toner image. A second lubricant having a viscosity greater than a viscosity of the first lubricant is applied between the metal member and the fixing belt at lateral edge portions of the fixing belt in the axial direction of the fixing belt that do not contact the recording medium.

摘要： An image forming apparatus includes a fixing device, a temperature detector, and a support member. The fixing device is removably installable in the image forming apparatus and includes a rotary fixing member to fuse a toner image on a recording medium, a fixing frame to support the fixing member, and an outer fixing cover provided to cover the fixing member and the fixing frame and having an opening from which a portion of a surface of the fixing member is exposed to the outside. The temperature detector is disposed opposing the fixing member to detect a temperature of the surface of the fixing member without contacting the fixing member when the fixing member is installed in the image forming apparatus. The support member supports the temperature detector to introduce the temperature detector into the inside of the fixing cover through the opening upon installation of the fixing member.
