There is provided a molding method of a thermosetting resin in which the formation of a flash can be prevented. This molding method comprises pouring or injecting the thermosetting resin into a mold, and then heating and molding it, and the method further comprises the step of locally heating an unnecessary gap and its peripheries of the mold, which are not concerned with the molding of the thermosetting resin into a desired article having a required shape, whereby the resin in the gap and its peripheries are promptly set to reduce the leakage of the resin into the unnecessary gap.

A developer-regulating member includes a rubber elastomer blade pressed against the surface of a developer-feeding member and a holder for holding the rubber elastomer blade. The holder is warped in the direction of flattening the face of part of the rubber elastomer blade, that face being pressed against the surface of the developer-feeding member.
