摘要： 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.

摘要： A developer level control blade is provided which can form a developer layer on a developer carrying member in a proper thickness and in a uniform state and can keep the developer, in particular, color toner particles from melt-adhering to the charge control face so that faulty images such as lines and non-uniformity can be kept from occurring. Also provided is a process for manufacturing this developer level control blade. The process for manufacturing the developer level control blade is characterized by having the steps of extruding a blade member material melted to liquefy, covering therewith a support member thin-plate metal member at an edge portion thereof to join the both together, and cooling the blade member material to solidify, followed by cutting in a preset length.

摘要： A cleaning blade for use in an electrophotographic apparatus, which rubs and eliminates residual toners. The cleaning blade is made up of polyrethane resin sheet controls chipping of a top end of the cleaning blade and reduces an abrasion of a photosensitive drum. The cleaning blade is prepared by mixing and hardening at least a prepolymer, which is obtained from butylene adipate polyester polyol, hexylene adipate polyester polyol and polyisocyanate, and a hardening agent including a low molecular weight polyol and potassium acetate so that a mol ration (&agr; value) of hydroxyl group to isocyanate group becomes not less than 0.7 and not more than 0.9.
