PROBLEM TO BE SOLVED: To provide a toner that prevents filming, and has excellent low-temperature fixability, high-temperature offset resistance, high glossiness, high color reproducibility, excellent charging property, and heat-resistant storage property.SOLUTION: A toner contains at least a polyester resin, and the polyester resin has a structure represented by any one of the following structural formulas (1) to (3). (1) R1-(NHCONH-R2-X-R3)n-, (2) R1-(NHCOO-R2-X-R3)n-, and (3) R1-(OCONH-R2-X-R3)n-, wherein: n=3; R1 represents an aromatic or aliphatic organic group; R2 represents a group derived from a resin of any one of polyester formed of at least one of a polycarboxylic acid and polyol and modified polyester in which polyester is modified with isocyanate; X represents a urea bond or a urethane bond; and R3 represents a group derived from a compound represented by a specific structural formula.SELECTED DRAWING: None |
