Abstract:
1. A toner for electrophotography, comprising a cyan toner, a magenta toner and a yellow toner, wherein each of the cyan toner, magenta toner and yellow toner comprises: an infrared absorbent; a binder resin; and a wax component, wherein the wax component contains a first wax having an endothermic peak in a temperature region of 60 to 90° C., the endothermic peak occurring in the temperature-rising stage of a DSC curve determined by a differential scanning calorimeter, and having a molecular weight distribution (weight-average molecular weight (Mw)/number-average molecular weight (Mn)) of 1.5 or less, and containing a component having a weight-average molecular weight (Mw) of 500 or less in an amount of 1% by mass of the wax component or less; and a second wax having an endothermic peak in a temperature region of 150 to 170° C., the endothermic peak occurring in the temperature-rising stage of a DSC curve determined by a differential scanning calorimeter, and having a molecular weight distribution (weight-average molecular weight (Mw)/number-average molecular weight (Mn)) of 1.1 or more.
