ABSTRACT:
An image forming apparatus includes: a belt member for bearing and moving a toner image; a tension roller for supporting the belt member and imparting tension to the belt member; a transferring device for transferring the toner image borne by the belt member to a recording material; a blade member which is in contact with a portion of the belt member supported by the tension roller to be at an acute angle on a downstream side with respect to a moving direction of the belt member and which removes toner on the belt member; a supporting member for supporting the blade member; a fixing member which fixes on the supporting member a substantial central portion of the blade member in a direction perpendicular to the moving direction of the belt member so that the blade member is rotatable; and a cushion member which is disposed between the fixing member and the blade member and which is deformed to urge the blade member, wherein the cushion member is disposed on a side opposite to the belt member with respect to the blade member.
