Abstract
A developing agent bearing member is manufactured such that a base is prepared, and a photosensitive layer is formed on the base. Then, the photosensitive resist layer is exposed with a pattern, and an uneven portion is formed on a surface of the developing agent bearing member by etching the pattern-exposed photosensitive resist layer.
Claims11
A method of manufacturing a developing agent bearing member, comprising the steps of:
- preparing a base;
- forming a photosensitive resist layer on said base;
- close contacting a portion of the photosensitive resist layer with a photomask;
- pattern exposing the close contacting portion while moving the photosensitive resist layer and the photomask to close contact photosensitive resist layer portions and the photomask in sequence;
- and
- forming an uneven portion on a surface of the developing agent bearing member by etching the pattern-exposed photosensitive resist layer.

A method of manufacturing a developing agent bearing member, comprising the steps of:
- preparing a base;
- forming a resin layer on said base;
- partially removing the resin layer to form a recessed portion;
- and
- filling a conductive material in the recessed portion from which resin is removed, thereby forming a projecting portion.
2 more elements
A method of manufacturing a developing agent bearing member, comprising the steps of:
- preparing a cylindrical base;
- forming a photo sensitive resist layer on said cylindrical base;
- preparing a cylindrical photomask, wherein an internal diameter of the photomask is larger than an external diameter of the cylindrical base;
- close contacting an inner cylindrical surface of the photomask with an outer cylindrical surface of the cylindrical base;
- pattern exposing the close contacting surfaces;
- and
- forming an uneven portion on a surface of the developing agent bearing member by etching the pattern-exposed photosensitive resist layer.
