Electronograph developing agent and method of manufacturing the same.

摘要

An electronograph developing agent containing polymerized particles of non-uniformly-shaped aggregated materials obtained by aggregation of colloidal oil drops (10), each having a developing-agent core (4) made of a pre-polymerized substantially spherical resin fine particle and a coloring agent (2) adhered onto the resin fine particle by a static force, and a monomer (3) for swelling the developing-agent core. <IMAGE> <IMAGE>
