    摘要: A device includes a fixing belt, a holder that holds the fixing belt, a pressing member that comes in contact with the fixing belt, a nip-forming-member arranged inside the fixing belt, that forms a nip by coming in contact with the pressing member, a supporting member that supports the nip-forming-member, a side plate to which the nip-forming-member and the supporting member are fixed, and a pressing mechanism that presses a pressing roller to the nip-forming-member via the fixing belt. The supporting member includes at least two plates. The two plates are separated from each other near a contact portion where the plates come in contact with the nip-forming-member. At least a part of each of the plates is a flat surface parallel to a direction of a load applied by the pressing mechanism. Portions of the two plates on a side distant from the contact portion are joined together.

    摘要: A fixing device includes a fixing member configured to be revolvable while being heated by a heat source; a counter rotator configured to form a nip between the fixing member and the counter rotator by applying a pressure to the fixing member in a contact state with the fixing member; a shield member disposed inside the fixing member to partially shield heat from the heat source; and a holding member attached to an end of the fixing member. The shield member includes a spacer configured to define a clearance to allow the holding member to be inserted into the fixing member from an end of the fixing member, the clearance being between the shield member and an inner surface of the end of the fixing member.

    摘要: A fixing device includes: a rotatable fixing member formed as an endless belt; a heat source to heat the fixing member; a nip-forming member being not rotatable and arranged inside the fixing member; and a pressure member arranged outside the fixing member and forming a nip between the pressure member and the fixing member. The nip-forming member is formed of a first heat transmission unit and a sliding sheet. The first heat transmission unit includes an abutting part abutting the fixing member with the sliding sheet therebetween, and a bent part or bent parts extending inside the fixing member at upstream or upstream and downstream of the nip in a transport direction of a recording medium. A retaining part to catch and retain the sliding sheet is provided at a tip of at least the bent part at upstream of the nip in the transport direction.

    摘要: A fixing device includes: a rotatable endless belt type fixing member; a pressurizing member that is opposed to the fixing member and rotates; and a nip forming member that is arranged inside the fixing member, and forms a nip part by contact with the pressurizing member through the fixing member. The nip forming member includes: a heat-uniformizing member having bent portions opposed to each other; a heat-insulating member arranged inside the heat-uniformizing member; a heat-absorbing member arranged on an upper surface of the heat-insulating member; and a sliding sheet that covers a nip side of the heat-uniformizing member, and is held between the bent portions of the heat-uniformizing member and the heat-insulating member. The heat-uniformizing member and the heat-insulating member are fastened to each other by fitting a fitting part formed on the heat-uniformizing member to a fitted part formed on the heat-insulating member.
