摘要:
A developing apparatus includes a developer container for containing a developer; a developer carrying member, disposed in an opening of the developer container, for carrying the developer; an elastic blade for forming a nip between the developer carrying member to regulate an amount of the developer on the developer carrying member; wherein a distance between the nip and an upstream end of the elastic blade with respect to a movement direction of the developer carrying member continuously increases from a longitudinal end of the elastic blade toward longitudinally central portion thereof.
摘要:
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.
摘要:
The invention provides an image forming apparatus comprising an intermediate transfer belt (5) composed of a resinous material, a transfer member for transferring a toner image (T) on the intermediate transferring belt (5) onto a transfer material (P), and an opposing member provided to be opposed to the transfer member across the intermediate transferring belt (5). The transfer member and the opposing member can be mutually pressured, and the intermediate transferring belt and the opposing member have an integrally measured microhardness smaller than 97°. Thus the invention provides an image forming apparatus capable of preventing a transfer unevenness caused at the transfer of the toner image from the intermediate transferring belt to the transfer material, and an intermediate transfer unit which is detachably attachable to the image forming apparatus.
