摘要

PROBLEM TO BE SOLVED: To provide a toner excellent in low temperature fixability, charging maintainability and heat-resistant storage stability.;SOLUTION: Toner particles include a resin component and a benzoic acid metal salt compound. The resin component has amorphous polyester and aliphatic crystalline polyester; the content of the amorphous polyester in the resin component is 50 mass% or more; the amorphous polyester has a total acid value of 3 mgKOH/g or more and 10 mgKOH/g or less and a total hydroxyl value of 40 mgKOH/g or more and 70 mgKOH/g or less; when defining the weight average molecular weights of the amorphous polyester (A) and the amorphous polyester (B) as Ma and Mb, the acid values thereof as Aa and Ab, the hydroxyl values thereof as OHa and OHb and mass ratios in the amorphous polyester as Wa (mass%) and Wb (mass%), respectively, 90≤Wa+Wb≤100, Wa>Wb, AaOHb and Ma
