摘要： An image forming apparatus includes a fixing device, 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.

摘要： A fixing device includes a fixing rotator over which a recording medium bearing an image is conveyed. A first heater heats the fixing rotator and generates heat evenly in a maximum conveyance span where the recording medium having a maximum width in a width direction of the recording medium is conveyed. The maximum width is available for the fixing rotator. A second heater heats the fixing rotator and generates heat in the maximum conveyance span. The second heater includes a first portion that generates heat in a first heat generation amount and a second portion that generates heat in a second heat generation amount that is greater than the first heat generation amount of the first portion.

摘要： A fixing device includes a fixing member; a heater to heat the fixing member; a nip forming member to contact the fixing member; and a pressure member, disposed opposite the nip forming member to press against the fixing member to form a fixing nip portion together with the nip forming member. The fixing device applies heat and pressure to fix an image transferred to a recording sheet when the recording sheet passes through the fixing nip. The nip forming member includes a first and second planar portions disposed at an upstream end and a downstream end, respectively, of the fixing nip portion, and the first planar portion and the second planar portion are continuous with a curved portion of the nip forming member. A guide member guides the recording sheet to bend in a direction opposite a back curl of the recording sheet generated in the fixing nip portion.

摘要： A fixing device includes a fixing rotator being rotatable and a heater to heat the fixing rotator. The heater includes a tube, a heat generator, disposed inside the tube, to generate heat, and a sealing portion, disposed at each lateral end of the tube in a longitudinal direction of the heater, to seal the tube. A reflector reflects heat radiated from the heater toward the fixing rotator. The reflector includes an outboard edge being disposed inboard from at least a part of the sealing portion in an axial direction of the fixing rotator.

摘要： A nip-forming member includes: a first nip-forming member configured to be a main body of the nip-forming member; and a second nip-forming member disposed on a surface of the first nip-forming member, the surface facing the inner circumferential surface, the second nip-forming member extending in a direction orthogonal to a rotating direction of the fixing belt. Both ends of the second nip-forming member on an upstream side and a downstream side of the rotating direction are bent in a direction away from the nipping part, in order to create a pair of side-wall portions, so that the second nip-forming member has a concave cross-section for accommodating the first nip-forming member. The second nip-forming member has a restraining portion at a position located on the side-wall portion created on the upstream side, the restraining portion being configured to restrain the first nip-forming member not to be detached from the concave cross-section.
