Abstract:
1. An electrostatic charge image developing toner comprising: toner particles comprising a polyester resin having an ethylenic unsaturated bond, and a reaction product of the polyester resin and a compound having an imidazoline structure, wherein the polyester resin has repeat units derived from a polyol and a polycarboxylic acid including a trimellitic acid, and a molar ratio of the repeat units derived from the trimellitic acid is from 0.1 mol% to 10 mol% with respect to the entire polymerization components of the polyester resin, and the reaction product exists in a surface part of the toner particles, and a weight ratio of the compound having an imidazoline structure is from 0.1% by weight to 10% by weight with respect to the total weight of the toner particles excluding the compound having an imidazoline structure.
