Abstract
A fixing device includes an endless fixing belt: a fixing belt holding member; a pressure member that makes a contact with the circumference of the fixing belt; a nip forming member that is disposed inside the fixing belt and forms a nip between the nip forming member and the pressure member; a nip supporting member that is made of a sheet metal; a side plate that supports the fixing belt holding member and the nip supporting member; and a pressure mechanism that presses the pressure member against the nip forming member with the fixing belt between the pressure member and the nip forming member. Both end surfaces of the nip supporting member are shear surfaces and one of the shear surfaces makes a contact with the nip forming member and the other shear surface is supported by the side plate.
