Patent ID: 8475987

Claim:
A yellow toner comprising at least a resin (a) having a polyester as a main component, a colorant, and a wax, and satisfying the following formulas (1) and (2) in DSC measurement: 40.0 ≦Tg (0.5)≦60.0 (1) 2.0 ≦Tg (4.0)− Tg (0.5)≦10.0 (2) (wherein Tg(0.5) is a glass transition temperature (° C.) obtained at a rate of temperature increase of 0.5° C./min, and Tg(4.0) is a glass transition temperature (° C.) obtained at a rate of temperature increase of 4.0° C./min) wherein when the concentration of the yellow toner in an ethyl acetate dispersion is C y1 (mg/ml), and the light absorbance at a wavelength of 422 nm of the dispersion is A(ethyl acetate) 422 , a relationship between C y1 and A(ethyl acetate) 422 satisfies the following formula (3): A (ethyl acetate) 422 /C y1 <0.45 (3) and when the concentration of the yellow toner in a chloroform solution is C y2 (mg/ml), and the light absorbance at a wavelength of 422 nm of the solution is A(chloroform) 422 , a relationship between C y2 and A(chloroform) 422 satisfies the following formula (4): 6.00 <A (chloroform) 422 /C y2 <14.4 (4).
