A photosensitive material processing apparatus according to the present invention includes a tank that has a body charged with a solution that processes the photosensitive material, the apparatus comprising a filter for purifying the processing solution, and a conduit for circulating the processing solution from a lower region of the tank body to an upper region of the tank body. Further, a pleated cartridge filter for use in a photosensitive material processing comprises a cylindrical pleated filter body formed by folding a filtering sheet member; and a blocking member, including a hole that communicates between an interior of the filter body and the outside, for blocking at least one end of the filter body, wherein a portion of the blocking member contacting the fitting portion is compressed when the blocking member is fitted to the fitting portion to closely contact the same.
