Abstract
An image forming method includes using yellow toner, magenta toner, cyan toner, and black toner in which each of the yellow toner, the magenta toner, the cyan toner, and the black toner includes a crystalline polyester resin having a constitutional unit derived from a linear chain aliphatic diol, an amorphous resin, a colorant, and a releasing agent. A carbon number of a linear chain aliphatic diol component forming the crystalline polyester resin contained in the black toner is 6 or more, and a carbon number of a linear chain aliphatic diol component forming the crystalline polyester resin contained in each of the yellow toner, the magenta toner, and the cyan toner is 3 or more and 5 or less.
