PURPOSE: To improve the fixability of an image by using a toner contg. a core encapsulated in a shell contg. a product obtd. by bringing a specified polyisocyanate and a specified amine into an interfacial polycondensation reac tion and contg. an electrically conductive material obtd. from an aq. dispersion of an electrically conductive material in a polymer binder on the core.
CONSTITUTION: A toner used contains a core encapsulated in a shell contg. a product obtd. by bringing a polyisocyanate and an amine into an interfacial polycondensation reaction and contg. an electrically conductive material obtd. from an aq. dispersion of an electrically conductive material in a polymer binder on the core. The polyisocyanate is selected from among PAPI27, PAPI135, 'Isonate 240(R)', etc. The amine is selected from among ethylenediamine, tetramethylenediamine, etc. High fixability of a final image is ensured.
