    • An image forming method including forming an electrostatic latent image on an image bearing member; developing the electrostatic latent image using a color toner and a transparent toner to form a color toner image and a transparent toner image thereon; transferring the color toner image and the transparent toner image to a recording material; and fixing the color toner image and the transparent toner image on the recording material. The color toner includes a polyester resin and a colorant, and the loss tangent of the color toner has a maximum peak at a temperature of from 80° C. to 160° C., and is not greater than 3 at the maximum peak. The transparent toner includes a crystalline polyester resin, and the loss tangent of the transparent toner has a maximum peak at a temperature of from 80° C. to 160° C., and is not less than 3 at the maximum peak.
