摘要： A developer apparatus includes a toner carrier roller with plural rows of convex sections arranged in width and circumferential directions of the roller. Top surfaces of the convex sections coincide with a curved surface of a single cylinder shaped like the roller. Convex section extending surfaces obtained by extending the top surfaces of the convex sections in the width direction overlap between convex sections belong to the same row and do not overlap between convex sections belonging to different rows. A width in the circumferential direction of a restriction nip formed by contact of an elastic abutting member of a restriction member with the roller is smaller than a spacing between two convex sections belonging to convex section rows that are adjacent in the circumferential direction.
