ENCAPSULATED TONER

PURPOSE:To enable fixing at high speed under low pressure by forming an outer thin shell for each oily ink droplet, suspending each obtained microcapsule into an aqueous emulsion and further forming another shell on each microcapsule. CONSTITUTION:The thin outer shell, for example, made of a polyamide is formed on each core material droplet containing a liquid or semisolid oily ink, and each obtained microcapsule is suspended into an aqueous emulsion, such as a styrene-acrylic resin emulsion, and dried to form another outer shell on each capsule. It is preferred to incorporate a magnetic powder, as well as an electric charge controller, a colorant, and the like in each core material and to control the content of a surfactant in the emulsion to
