摘要：
A color toner for electrophotography having excellent fixability and void resistance is capable of forming a high-quality image. The color toner for electrophotography comprises a binder resin and is a magenta toner, and used in combination with at least any of yellow toner and cyan toner. The storage modulus (G′100) (100° C.) of the binder resin is (1/1.1) to (1/10) times the storage modulus (G′100) (100° C.) of a binder resin contained in the yellow toner and the cyan toner. In addition, the color toner for electrophotography comprises a binder resin, C.I. pigment Violet 19, and an infrared absorbent. The color toner is a magenta toner used in combination with at least any of an yellow toner and a cyan toner. The content of the infrared absorbent in the magenta toner is higher than the content of an infrared absorbent in the yellow toner and the cyan toner.
