Abstract

PURPOSE:To enhance electric charging performance and fixability by using an encapsulated toner having a rugged form with wrinkled parts and a specified particle diameter distribution. CONSTITUTION:The encapsulated toner particles having each a rugged form with wrinkled parts and each is composed of a core material comprising a solvent, a fixing resin 1 dissolved in said solvent into a solution, and coloring pigment particles 2 dispersed in said solution, and an shell 3 encapsulated by executing the interfacial polymerization method or the in situ polymerization method to produce a resin insoluble and nonswellable in said solvent on the circumference of each of the core particles, and the obtained capsules have a number average particle diameter of 5-17mum, and the following distributions in which the number of the particles having diameters of <=3mum amounts to <=10% of the total particle number, and the number of particles having diameters of >=20mum amounts to <=5%, thus permitting the obtained encapsulated toner to be good in rising of charging and fixability.
