Abstract
Official abstract text for this publication.
An electrostatic charge image developing toner is configured of a polycondensate of a polyol and a polycarboxylic acid including a trimellitic acid, includes a polyester resin with an ethylenic unsaturated bond, and has toner particles including a reaction product of the polyester resin and a compound having an imidazoline structure in a surface part, a molar ratio of the trimellitic acid is from 0.1 mol % to 10 mol % with respect to the entire polymerization components of the polyester resin, 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.
First claim
Opening claim text (preview).
What is claimed is: 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% w…
