Abstract:
1. A waste toner collecting container fixedly connected to an assembly of a development unit and a photoreceptor unit, the waste toner collecting container comprising: a first wall; a second wall; a bottom wall that extends obliquely downward relative to the first wall and the second wall to a waste toner collecting inlet through which waste toner enters the waste toner collecting container as the photoreceptor rotates, the waste toner collecting inlet being below the second wall; a top wall mounted on top of the first wall and the second wall; plural reinforcing ribs spaced apart along an axial direction of the photoreceptor, each of the plural reinforcing ribs including first and second surface portions perpendicular to the axial direction, the first and second surface portions being on opposite sides of each of the plural reinforcing ribs, each of the plural reinforcing ribs protruding from an inner surface of the bottom wall and an inner surface of the first wall to form a concave profile that opens to an inner surface of the second wall, the inner surface of the first wall facing the photoreceptor unit and the development unit; and a waste toner discharging outlet formed in the top wall at an end of the top wall along the axial direction of the photoreceptor, the plural reinforcing ribs being spaced apart from the waste toner discharging outlet along the axial direction, wherein the development unit is configured to supply toner to the photoreceptor in the photoreceptor unit, wherein the photoreceptor unit is configured to form a toner image on an outer surface of the photoreceptor and includes a cleaning component that removes waste toner that remains on the outer surface of the photoreceptor after the toner image is transferred to a recording medium, and wherein the waste toner collects between the first wall and the second wall and is discharged from the collecting container through the top wall via the waste toner discharging outlet.
