Patent ID: 8497056

Claim:
A magenta toner comprising a toner particle, which comprises at least a resin (a) having a polyester as a main component, a colorant, and a wax, wherein when the glass transition temperatures of the magenta toner measured by DSC at a rate of temperature rise of 0.5° C./min and 4.0° C./min are defined as Tg(0.5)(° C.) and Tg(4.0)(° C.) respectively, a relationship between the Tg(0.5) and the Tg(4.0) satisfies the following formulas (1) and (2), 40.0 ≦Tg (0.5)≦60.0 (1) 2.0 ≦Tg (4.0)− Tg (0.5)≦10.0 (2) wherein, when preparing a solution of which the magenta toner is dissolved in ethyl acetate, and defined the concentration of the thereof as C m1 (mg/ml), and the light absorbance thereof at a wavelength of 538 nm as A(ethyl acetate) 538 , the ratio of A(ethyl acetate) 538 to C m1 satisfies the following formula (3), A (ethyl acetate) 538 /C m1 <0.15 (3), wherein, when preparing a solution of which the magenta toner is dissolved in chloroform, and defined the concentration of the thereof as C m2 (mg/ml), and the light absorbance thereof at a wavelength of 538 nm as A(chloroform) 538 , the ratio of A(chloroform) 538 to C m2 satisfies the following formula (4) 2.00 <A (chloroform) 538 /C m2 <6.55 (4) wherein the toner particle has a surface layer (B) with a resin (b) as a main component on a surface of a toner base particle (A) containing at least the resin (a), the colorant, and the wax, and wherein the resin (b) is a resin selected from a urethane resin, a polyether resin, and a vinyl resin containing a vinyl unit represented by the following general formula ( 1 ), wherein R 1 represents an aromatic or aliphatic hydrocarbon group, and R 2 represents a proton or an aliphatic hydrocarbon group.
