ABSTRACT:
A magnetic particle brush developing carrier used for electrostatic latent image developing is disclosed, comprising a magnetic particle having a surface coating comprising two kinds of fluoro-type resins, with one of the resins having a higher critical surface tension than the other. The carrier maintains its triboelectric properties even after extended use, it reaches charge saturation after a short period of triboelectrification, and it has excellent charge stability against environmental change.
