PURPOSE:To easily produce a toner contg. a photoconductive agent and a functional property imparting agent in the shell layer and having a tough coating film of a controlled thickness at a stroke without passing through a process. CONSTITUTION:At least fine resin particles are stuck on the surfaces of core particles, the core particles are treated with a mixture prepd. by adding at least a functional property imparting agent and/or a photoconductive agent to a solvent dissolving the fine resin particles and the treated particles are dried and recovered. The resulting toner has superior electrophotographic characteristics such as electrostatic chargeability and flowability, ensures stable quality and gives a clear image by a simple low-cost process. |
