Abstract
A toner for electrostatic latent image development is disclosed. The toner for electrostatic latent image development includes toner particles, the toner particles includes a binder resin and a release agent, and the toner has a linear thermal expansion coefficient in accordance with JIS K 7197-1991 of from about 6×10−5/C.° to about 1×10−3/C.°. An electrostatic latent image developer, a toner cartridge, a process cartridge, and an image forming apparatus are also disclosed.
Claims16
A toner for electrostatic latent image development comprising toner particles, the toner particles including:
- a silicone resin,
- a binder resin comprising a polyester resin containing an alcohol component and a polyhydric carboxylic acid component, the polyhydric carboxylic acid component comprising a component derived from terephthalic acid and fumaric acid, and the alcohol component comprising a component derived from ethylene glycol and a component derived from a member selected from the group consisting of an ethylene oxide adduct of bisphenol A, a propylene oxide adduct of bisphenol A, and both thereof,
- a release agent,
- a colorant, and
- a C.I. Pigment Yellow 180, of which amount is smaller than an amount of the colorant, wherein, the toner has a linear thermal expansion coefficient in accordance with JIS K 7197-1991 of from 6×10−5/° C. to 1×10−3/° C.;
- wherein
- the number-average particle size distribution index (GSDp) of the toner is in the range of from 1.20 to 1.27.
