ABSTRACT:
A magenta toner for developing electrostatic images provided which contains a binder resin and a colorant, wherein the colorant includes a mixed crystal of two or more colorants and when a solid patch is fixed on art paper complying with the ISO standard by using this toner, a resulting fixed image color satisfies at least one of the following formulae (b*)<0.85 (a*)−67.92; and (b*)>−7.94(a*)+591.85. The color difference ΔE between the color of the fixed image and the color characterized by L*: 46.6, a*: 75.1 and b*: −4.4 is preferably less than 6. The colorant is preferably a mixed crystal of a quinacridone colorant and a monoazo colorant. Moreover, the invention provides a method for producing the magenta toner, a developer containing the magenta toner, and an image-forming method using the magenta toner.
