Abstract
Provided is a color image forming process using colorant-containing toners of multiple colors containing colorants respectively having different resistances, wherein each of the colorant-containing toners contains an amorphous resin, a crystalline polyester resin, and a mold release agent, at least the crystalline polyester resin contained in the colorant-containing toner other than the colorant-containing toner containing a colorant having the lowest resistance contains a hybrid crystalline polyester resin formed by bonding a crystalline polyester polymerized segment and an amorphous polymerized segment, and the content of the amorphous polymerized segment in the hybrid crystalline polyester resin contained in the colorant-containing toner other than the colorant-containing toner containing a colorant having the lowest resistance is greater than the content of the amorphous polymerized segment in the crystalline polyester resin contained in the colorant-containing toner containing a colorant having the lowest resistance.
