Abstract
A high-precision injection-molded toner-amount regulating elastic blade used for high-quality development, particularly, an elastic blade in which the generation of rust is prevented by suppressing peeling of a plated layer from a supporting plate, is provided. The elastic blade is used in an image forming apparatus in which an electrostatic latent image formed on an image bearing member is developed using a toner to provide a visual image. A preserved steel plate obtained by plating a zinc alloy on surfaces of an iron material is used as the supporting plate. A rubber elastic member for regulating the amount of the toner is supported on the supporting plate.
