Patent ID: 7923190

Claim:
A toner which comprises toner particles containing at least a binder resin, a colorant, an ester compound and a low melting material; the ester compound being an ester of dipentaerythritol with a carboxylic acid having 18 or more to 25 or less carbon atoms; where the melting point of the ester compound is represented by Tm (A) (° C.) and the melting point of the low melting material is represented by Tm (B) (° C.), the toner satisfying the relationship of: Tm (B) <Tm (A) ; wherein the ester compound has a solubility S(A) in a styrene acrylic resin, of 2.5% or less, the styrene-acrylic resin has a glass transition temperature of 54.0° C.±1.0° C., a number-average molecular weight of 20,000±2,000 and a weight average molecular weight of 200,000±20,000; and wherein the low melting material has a solubility S(B) in the styrene acrylic resin, of from 5.5% or more to 20.0% or less, and S(A)<S(B).
