There is provided a fastening target member attached to an attachment member by a fastening member that includes a head and a shaft. The fastening target member has a surface, at least one insertion hole that allows the shaft of the fastening member to be inserted therethrough, and a fastening member removal structure that is formed in the surface of the fastening target member where the head of the fastening member is disposed and that has a pair of grooves. The pair of grooves face each other with the at least one insertion hole interposed therebetween. The pair of grooves are each formed from an inner circumferential side relative to the outer diameter of the head of the fastening member to an outer circumferential side relative to the outer diameter of the head of the fastening member.

A fixing device includes a heating member that heats a toner image on a recording medium and includes a rotatable belt member, a heat source, a pressing member, a sliding sheet, and a pressure-applying member. The pressing member presses the belt member against the pressure-applying member. A surface of the pressing member that opposes the belt member includes a flat portion or a recessed portion having a radius of curvature of approximately 100 mm or more. The sliding sheet is disposed between the belt member and the pressing member and includes a sliding layer containing cross-linked polytetrafluoroethylene, the content of which in resin contained in the layer is approximately 25 mass % or more and approximately 75 mass % or less. The pressure-applying member presses the recording medium against the belt member and rotates to transport the recording medium while nipping it between itself and the belt member.
摘要:
A fixing device includes a fixing rotary body that heats toner while rotating and fixes the toner on a recording medium, a pressurizing rotary body that sandwiches and pressurizes the toner and the recording medium by the fixing rotary body, and a supporting part that supports the fixing rotary body from the inside so that a peak pressure on an outlet side of the recording medium becomes equal to or lower than a peak pressure on an inlet side, in a contact part where the fixing rotary body and the pressurizing rotary body come into contact with each other.
