A mold for use in producing a molded body of an elastomer has a holding layer and a releasing layer on an inner periphery surface of a main body of a die. The releasing layer is formed of an addition two-component liquid silicone having a polysilazane-based or polysiloxane-based chain as a main chain, contains 0.5 mass % or less of a component which volatilizes at a curing temperature of a liquid elastomer raw material, does not contain silica, has International Rubber Hardness Degree of 50 to 85 degrees, and contains a solid lubricant having an average particle size of 2 to 20 μm. The present invention also provides a method for manufacturing a blade for an electrophotographic apparatus by using the mold and a developer amount controlling blade having specific load length ratio and ten-point average roughness in which a blade member is manufactured with the method. |
