Abstract A cleaning device for an electrophotographic copying apparatus comprising a photosensitive medium having liquid collection grooves formed at the opposite end portions thereof, and a cleaning blade of resilient material having an edge adapted to bear against the surface of the photosensitive medium. The cleaning blade has projections formed at the opposite ends thereof so that when the blade is brought to its cleaning position, the inner side walls of the projections thereof may keep liquid-tight contact with the inner side walls of the liquid collection grooves. Thus, relative sliding movement between the blade and the photosensitive medium removes any amount of developing liquid remaining of the surface of the photosensitive medium after an image transfer has been completed.
A cleaning device for an electrophotographic apparatus including a photosensitive medium, comprising means defining liquid collection grooves at the opposite end portions of said photosensitive medium, and a cleaning blade of resilient material having an edge adapted to bear against the photosensitive medium, said cleaning blade having projections formed at the opposite ends thereof so that the inner side walls of said projections may keep liquid-tight contact with the inner side walls of said liquid collection grooves, whereby relative sliding movement between said blade and said photosensitive medium removes any amount of developing liquid remaining on said photosensitive medium after an image transfer has been done. CM,2Aning device as defined in claim 1, wherein said projections of said cleaning blade comprise guide members attached to the blade.
Claim 2
Dependent Claim
41 words
A cleaning device as defined in claim 1, further comprising means for moving said cleaning blade from the surface of said photosensitive medium into a carrier liquid reservoir to maintain said blade in wet condition during the suspension of cleaning operation.
Claim 3
Dependent Claim
31 words
A cleaning device as defined in claim 1, further comprising means for orienting said cleaning blade in a counter direction with respect to the direction of movement of said photosensitive medium.
