Device for cleaning photosensitive drum of wet type printer

Abstract

A photosensitive drum cleaning device of a wet type printer includes: a cleaning blade disposed on a photosensitive drum to contact and wipe an outer circumference of the rotating photosensitive drum, for removing a developer that has not been transferred to a transfer belt but remains on the photosensitive drum; and a developer drain holder for collecting and discharging the developer removed by the cleaning blade. The cleaning blade includes first and second guide wings which are respectively formed at opposite sides of a contact portion of the cleaning blade and the photosensitive drum and which have a predetermined height. The guide wings prevent the developer that is wiped by the cleaning blade from streaming down over the opposite sides of the cleaning blade. The guide wings are formed integrally with the cleaning blade to have a width that is thinner than the thickness of the cleaning blade. Accordingly, due to the presence of the pair of guide wings, the residual developer wiped by the cleaning blade is prevented from streaming down over the opposite sides of cleaning blade.
