Image forming apparatus with transfer belt pressing member

摘要

An image forming apparatus comprising: an endless belt that is wrapped around and so transported by a plurality of rollers; rotating members which are disposed adjacent to the endless belt such that an image is transferred onto a sheet while the sheet passes between the rotating members and the endless belt; pressing means that are disposed in a crosswise direction of the endless belt so as to be opposite to the rotating members with respect to the endless belt and press the endless belt against the rotating member in the vicinity of the position where the endless belt is in close proximity to the rotating member; and edge reinforcing means for increasing pressing forces of the pressing means that act on both edges of the endless belt in the crosswise direction thereof so as to become greater than a pressing force of the pressing means that acts on the center of the endless belt in the same direction.
