Abstract
A magenta toner includes a binder resin including an amorphous resin; a magenta pigment comprising a naphthol pigment; and a release agent. The magenta toner has a glass transition temperature of from 19 to 40° C. The naphthol pigment has an X-ray diffraction pattern having plural peaks in the following range: 0°≦2θ≦35° wherein θ is a Bragg angle. The sum of half widths of the respective peaks is from 5 to 10°.
