ABSTRACT:
The invention provides an electrostatic latent image developing dry toner composition that is used for forming images on both sides of a recording material, in which the toner contains calcium compound particles, and the amount W of the calcium compound particles added and the size d of the calcium compound particles meet the requirement of 5<W/d<500 . . . (1) (W: ratio to the total amount of toner (% by weight), d: volume average particle size (μm)), a developer constituted by the toner composition and a carrier, and an image forming method using the toner composition.
