Abstract:
1. A toner, comprising: a binder resin; a colorant; a release agent; and a layered inorganic mineral, wherein the toner is manufactured by a method comprising: dissolving or dispersing the binder resin, optionally together with a precursor of the binder resin, the colorant, a dispersion of the release agent, and the layered inorganic mineral, in an organic solvent to prepare a toner constituent liquid; and dispersing the toner constituent liquid in an aqueous medium to prepare an emulsion containing the toner, and wherein a difference in absorbance ratio between the toner heated for 1 minute in an atmosphere of 100° C. and the toner stored in an atmosphere of 23° C. is from 0.1 to 0.2, wherein the absorbance ratio is a ratio of an absorbance specific to the release agent to an absorbance specific to the binder resin, measured by a Fourier transform infrared—total reflectance (FTIR-ATR) method.
