摘要

PURPOSE: Provided is a nonmagnetic toner which is reduced in the pollution of an environmental member due to the adhesion of an external additive to toner particles, shows excellent static stability to environment, satisfactory developability and high transfer property and can maintain high resolution for a long time. CONSTITUTION: The nonmagnetic toner comprises a nonmagnetic toner particle containing at least a binder resin and a colorant and an inorganic fine powder, wherein the nonmagnetic toner particle comprises at least one kind of compound represented by the formulas 1 and 2, and the content of the compound is 5-1,000 ppm. In the formulas 1 and 2, R1 to R6 are identical or different one another and are independently a C1-C6 alkyl group; and R7 to R11 are identical or different one another and are independently a C1-C6 alkyl group. Preferably the toner has an average circularity of 0.940-0.995 and a weight average diameter D4 of 3-10 micrometers.
