ABSTRACT:
A developing blade10is insert molded by forming a rib portion13which projects from an end portion in the longitudinal direction of a blade body12in the transverse direction of the blade body12, opposite to the contact surface12aside of the blade body12, on the blade body12in contact with the developing roll of the developing blade10and forming the gate21G of a metal mold20in which a metal plate11as an insert member has been installed only in a cavity21bcorresponding to the above rib portion13. Therefore, a developing blade10without burrs and recesses on its contact surface with the developing roll or without welds can be easily manufactured.
