ABSTRACT:
An image forming apparatus for an electrophotographic process utilizes an agglomerate of toner powder so as to avoid scattering of toner powder. When the agglomerate is crushed or de-agglomerated to fine toner powder, only toner powder having a proper particle size for electrophotography is selected by a mesh member through which the toner must pass. The process can be utilized for a single component toner developing system and a component toner developing system.
