Developing assembly, developer quantity control blade and process for manufacturing developer quantity control blade

A process for manufacturing a developer quantity control blade which controls the quantity of a developer transported by a developer-carrying member;

• the process comprising the steps of:
• extruding a material for a blade member onto a charge control face face-transferring sheet in a uniform thickness, followed by solidification to make a blade member;
• laminating the supporting member to the blade member on its side not serving as the charge control face, to bond them together to form a laminate;
• and
• cutting the laminate to have the shape of the developer quantity control blade as a final shape.

• and
• cutting the laminate to have the shape of the developer quantity blade as a final shape;
• and
• in at least any one of stages before the step of lamination, after the step of lamination, before the step of cutting and after the step of cutting, the charge control face is so made rough as to have a ten-point average roughness Rz of from 0.3 μm to 20 μm.
