Abstract: A developer regulating member includes a thin plate having a spring property and a polyamide-containing rubber layer disposed on the thin plate. The polyamide-containing rubber layer contains a polyamide having the Shore D hardness between 25 and 65 both inclusive. A developing apparatus includes a developer container for containing a monocomponent developer of negative charging property, a developer carrying member provided in an opening portion of the developer container, for carrying the developer, and a regulating member for forming a nip together with the developer carrying member and regulating a thickness of a developer layer on the developer carrying member. A surface of the regulating member forming the nip is comprised of a polyamide-containing rubber layer containing a polyamide havingthe Shore D hardness between 25 and 65 both inclusive.

Abstract: An elastic blade is used in a developing device for controlling the amount of a developing agent (or a thickness of a developing agent fed onto a developing sleeve). The blade has on its surface an electrifying layer formed out of a specific polyamide elastomer. The polyamide elastomer is comprised preferably of a block copolymer of polyamide and polyester.
