摘要:
An objective is to provide a toner and a method of manufacturing the toner by which a charging amount of toner is kept maintaining to be an appropriate value for a long duration, print images with no fog, together with high density obtained even after heavy-duty printing are obtained, and no contamination within an apparatus caused by toner scattering is generated. Also disclosed is an electrophotographic toner possessing at least a resin and a colorant, wherein the colorant comprises a compound represented by Formula (1) or a lake product of the compound, and the colorant extracted from the electrophotographic toner surface has a colorant surface-exposure amount index of 0.3-0.8.
