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.

Abstract: A toner container comprises a toner storage section for providing a developer unit with a supply of toner, and a residual toner collect section integrally formed with the toner storage section and adapted to collect residual toner after an image has been developed. The present invention is intended to facilitate positioning, loading and unloading of the toner container, and also enable the toner to be smoothly supplied without being scattered from the toner container.The toner storage section includes a longitudinally extending rotary shaft and a resiliently deformable blade mounted to the rotary shaft. The toner storage section has a bottom, a first side wall, and the other or second side wall. A portion of the blade at a location corresponding to the first side wall is curved larger than a portion of the blade at a location corresponding to the second side wall.
