Abstract

Abstract PURPOSE:To render outer shells dense and to enhance the volume resistivity of an encapsulated toner by forming the outer shell made of a resin contg. 1- 30wt% epoxy resin on the circumference of a core material contg. a colorant and a binder. CONSTITUTION:An encapsulated toner is obtained by forming an outer shell made of at least one kind of resin selected from a group of polyurea, polyurethane, polyamide, and polyester, contg. 1-30, preferably 2-25, especially, 5- 20wt% epoxy resin on the circumference of a core material contg. a colorant, e.g., carbon black or the like black toner, or blue, red, yellow, or the like colored toner, and a binder, such as polyolefin, polystyrene resins, or polyurethane.
