ABSTRACT:
A construction for preventing a scattering or spillage of a developing solution applied to the peripheral surface of a rotating photosensitive drum beyond the lateral ends thereof in an electrophotographic copying machine of wet developing type. Two end plates which rotate with the drum are each provided with an axially extending cylindrical hub portion on which a stationary flow guide ring is sealingly engaged. A lateral flow of solution on the peripheral drum surface is guided along the guide plate to flow down without scattering the flow and is collected in a reservoir below the drum.
