Abstract
A cleaning device is disposed substantially vertical above a photosensitive drum for the purpose of constructing a compact electrophotographic printer. The cleaning device includes a housing that accommodates an auxiliary toner conveying part and a sheet-like resilient member. A cleaning brush is also disposed in the housing so that a gap of 1-3 mm is formed between the cleaning brush and the auxiliary toner conveying part and resilient member. During an image forming operation, toner accumulates between the cleaning blade and the cleaning brush and is conveyed upward through the gap between the cleaning brush and the auxiliary toner conveying part and resilient member. The toner drops onto the cleaning brush near the top thereof and is conveyed by the cleaning brush to a screw. The screw discharges the toner from the cleaning device.
