<p>PROBLEM TO BE SOLVED: To provide a toner that exhibits an excellent heat-resistant storage property, hot-offset resistance, and low-temperature fixability even when a resin including a polylactic acid skeleton is used as a substantial main component.SOLUTION: A toner contains, as a binder resin, a copolymer in which a polyester segment (B) having a polyhydroxycarboxylic acid skeleton is grafted to the terminal of a crystalline polyester segment (A) formed by condensing a tri- or more-valent alcohol or carboxylic acid, diol, and dicarboxylic acid, where the polyhydroxycarboxylic acid skeleton comprises an L body and D body of a polyhydroxycarboxylic acid being an optical activator, and their weight ratio L/D is 0.14 or more and 7 or less.</p> |
