Abstract:
A fixing device including a heated endless belt, a first member, a second member, a pressure roller, a guide member, a sliding member, and a lubricant application member. The first member is a non-rotating body inside of the belt and together with the second member tensions the belt. The pressure roller is outside the belt and presses against the first member via the belt, thereby forming the fixing nip. The guide member is inside of the belt and has a guide surface that guides the belt in circulation and a recess opening into the guide surface. The sliding member is between the belt and the first member. The lubricant application member is fitted in the recess and applies lubricant to the belt. The guide surface has an arc shape that is interrupted by the recess in a cross section perpendicular to an axis of rotation of the pressure roller.

Claim (Index 11):
An image forming device including a fixing device that fixes an unfixed image on a sheet being conveyed, the fixing device comprising:\n a heated endless belt; a first member that is a non-rotating body disposed inside of the belt; a second member disposed inside of the belt, cooperating with the first member to tension the belt; a pressure roller disposed outside of the belt that presses against the first member via the belt, thereby forming the fixing nip between the pressure roller and the belt; a guide member disposed inside of the belt that has a guide surface and guides the belt via the guide surface being in surface contact with an inner circumferential surface of the belt in circulation; a sliding member disposed between the belt and the first member; and a lubricant application member that applies lubricant to the inner circumferential surface of the belt, wherein the guide member has a recess opening into the guide surface, the guide surface has an arc shape that is interrupted by the recess in a cross section taken on a virtual plane perpendicular to an axis of rotation of the pressure roller, and the lubricant application member is fitted in the recess.
