Abstract: Projection row (2) and recess row (3) are alternately and successively formed in a direction (Y-direction) perpendicular to a direction (X-direction) of their rows, thereby forming a corrugated cross-sectional shape of a cross-sectional wave shape. Between projection row (2) and recess row (3), there is provided inclined wall surface (4) having a wave shape in plan view. Each of projection row (2) and recess row (3) has a shape in a cross-section along X-direction that is formed into a corrugated cross-sectional shape of a wave shape. Pitch and height difference between valley portion (5) and crest portion (6) in the corrugated cross-sectional shape along this X-direction are smaller, as compared with a relationship between projection row (2) and recess row (3) in the corrugated cross-sectional shape along Y-direction.

A roller body of a supply roller includes a contact surface that contacts the peripheral surface, and a second side surface located at an end of the contact surface in the axial direction. The restricting member has a one side and another side. The one side is opposed to the second side surface in the axial direction. The another side is opposed to the first side surface in the axial direction with a gap. The gap is communicated with an interior space of a developer accommodating frame such that the developer is capable of moving away from a nip position between the supply roller and the developing roller toward the bottom wall of the developing frame in the gap.
