摘要：
Toner particles, comprising: a binder resin; a colorant; a release agent; and a particulate resin which is present on at least a portion of a surface of said toner particles, wherein said particulate resin has a glass transition temperature of from 50 to 90°C; wherein the ratio (Dv/Dn) of a) the volume average particle diameter (Dv) of the toner particles to b) the number average particle diameter (Dn) thereof is from 1.00 to 1.40; and wherein the ratio of 1) an area of the surface of said toner particles which are covered by said particulate resin to 2) the total area of said surface is from 1 to 90 %. Also provided is a developer including the toner particles and a developing method using the toner particles.
