Abstract
An developer for developing a latent image with a developing agent such as toner. The developer includes a developing sleeve for holding the developing agent on its surface, in which magnetic poles are provided in the developing sleeve; a equalizer bar for equalizing the amount of the developing agent on the surface of the developing sleeve; a pressing member to press the equalizer bar onto the developing sleeve. In the developer, a radius of curvature of the equalizer bar is between 0.5 mm and 15 mm, and the developing sleeve is processed to have a jagged surface which is defined by a glossiness between 2% Gs and 1400% Gs (20.degree.).
Claims5
A method of finishing a surface of a means for holding a developing agent thereon in a developing apparatus for developing a latent image with a developing agent, comprising the steps of:
- providing a smooth surface of the holding means;
- sand-blasting said surface of the holding means with amorphous particles;
- and
- sand-blasting the surface of the holding means with spherical particles, after said sand-blasting step with amorphous particles.
