Patent ID: 7794909

Claim:
A toner comprising: a toner particle that comprises at least (a) resin having polyester as the main component, colorant, wax, and (b) urethane resin, wherein the hydroxyl value per specific surface area of the toner particle is at least 0.5 mg KOH/m 2 and no more than 10.0 mg KOH/m 2 , the toner has a Tg(0.5) of at least 40° C. and no more than 60° C. and a Tg(4.0)-Tg(0.5) of at least 2.0° C. and no more than 10.0° C., where Tg(0.5) is the glass transition temperature of the toner measured with a differential scanning calorimeter (DSC) at a rate of temperature rise of 0.5° C./min and Tg(4.0) is the glass transition temperature of the toner measured with the DSC at a rate of temperature rise of 4.0° C./min, wherein the toner particle is a capsule-type toner particle that has a surface layer (B) comprising the (b) urethane resin as the main component, at the surface of a toner base particle (A) that comprises at least the (a) resin comprising polyester as the main component, the colorant and the wax and the (b) urethane resin has a hydroxyl value of at least 10 mg KOH/g and no more than 200 mg KOH/g.
