TONER

摘要

Provided is a toner that has satisfactory chargeability and hardly causes a reduction in image density, fogging, and density unevenness in various environments ranging from a low-temperature and low-humidity environment to a high-temperature and high-humidity environment. The toner includes toner particles obtained by fixing resin particles to toner base particles each containing resins, in which: the resins contain 50.0 mass % or more of a styrene-acrylic resin and 1.0 to 40.0 mass % of a polyester resin A; the polyester resin A contains 0.10 to 30.00 number % of an isosorbide unit; the fixing amount of the resin particles to the toner base particles is from 0.1 to 5.0 parts by mass with respect to 100 parts by mass of the toner base particles; and the glass transition temperature of the resin particles is higher than the glass transition temperature of the toner base particles.

主权项

1. A toner, comprising toner particles obtained by fixing resin particles to toner base particles each containing resins and a colorant, wherein:
the resins comprise a styrene-acrylic resin and a polyester resin A; a content of the styrene-acrylic resin is 50.0 mass % or more with reference to the resins; a content of the polyester resin A is 1.0 mass % or more and 40.0 mass % or less with reference to the resins; the polyester resin A has a unit represented by the following formula (1), and a ratio of the unit represented by the following formula (1) is 0.10 number % or more and 30.00 number % or less with reference to the number of all units constituting the polyester resin A; a fixing amount of the resin particles to the toner base particles is 0.1 part by mass or more and 5.0 parts by mass or less with respect to 100.0 parts by mass of the toner base particles; and when a glass transition temperature of the toner base particles is represented by Tg1 (° C.) and a glass transition temperature of the resin particles is represented by Tg2 (° C.), the Tg2 is higher than the Tg1.
