Abstract

Provided is a mold (10) to be used for manufacturing a developing blade. In the mold (10), blank areas are retained over an elongated hard plate and on the two sides in a longitudinal direction, and an elastic member to contact a developer is adhered between the blank areas. An overflow portion (SC-1), which continues as a space to a cavity (MC-1) formed in a shape corresponding to the elastic member thereby to recover an over-flown material, is formed in a corresponding preset region between the two blank areas. The overflow portion can be left as it is over the developing blade product and between the two blank areas, so that it need not be removed after the molding operation. Thus, it is possible to simplify not only the mold structure but also the working operation.
