摘要： An image forming apparatus may include a main body having a surface. The main body may accommodate a photosensitive member disposed away from the surface and along a conveying path and a fuser. The fuser may be disposed downstream from the photosensitive member along the conveying path and have a portion disposed further away from the surface than the photosensitive member. The fuser may include an endless belt and a nip plate. The nip plate may include a first surface with lubricant thereon that faces an inner surface of the endless belt, and a second surface that extends from an end of the first surface. The second surface may be spaced apart from the inner surface of the endless belt and include a furthest downstream portion of the nip plate.
