ABSTRACT:
A residual toner collecting unit for collecting residual toner includes a collection chamber in communication with a residual toner collecting opening through which residual toner is received. Within the collection chamber, a conveyance roller is mounted to receive the residual toner coming through the residual toner collecting opening and is rotated to convey the residual toner in the direction of rotation. In addition to the conveyance roller, a blade is located within the collection chamber and is mounted to a rotary shaft. The blade is elastically deformable in the direction of the rotation of the blade and has a distal end which is in surface contact with the peripheral surface of the conveyance roller.
