Abstract: A mold 30 for use in producing a development blade 1, which is to be formed by adhering an elastic member to an elongated-shaped hard plate 2 along the longitudinal direction LD thereof, wherein the hard plate has notched portions on both side portions in the longitudinal direction thereof and the elastic member is molded to skip the notched portions, comprises: a cavity portion CA having a shape in accordance with the shape of the elastic member; and a gate portion 35 for injecting a material into the cavity portion CA, wherein the gate portion 35 is positioned, in the longitudinal direction LD, either on a border CL between each notched portion and the center portion side of a main body of the cavity portion or on the outer side of the border or within 10 mm on the inner side of the border. Since the gate portion 35 of the cavity CA is optimally positioned in the mold, the cavity is reliably filled with a material in a case where a small-diameter portion corresponding to the notched portion exists in the cavity, whereby a development blade can be produced with suppressing short shot and generation of flash.
