Abstract
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.
