Yellow toner

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 Cy1 (mg/ml), and the light absorbance at a wavelength of 422 nm of the dispersion is A(ethyl acetate)422, a relationship between Cy1 and A(ethyl acetate)422 satisfies the following formula (3):
• A(ethyl acetate)422/Cy1<0.45 (3)
• and
• when the concentration of the yellow toner in a chloroform solution is Cy2 (mg/ml), and the light absorbance at a wavelength of 422 nm of the solution is A(chloroform)422, a relationship between Cy2 and A(chloroform)422 satisfies the following formula (4):
• 6.00<A(chloroform)422/Cy2<14.4 (4).
