ABSTRACT:
An image forming method for forming a full color toner image by overlaying four color electrostatic image developing toners of black, yellow, magenta and cyan, wherein at least one of the four color electrostatic image developing toners is a toner containing a large diameter external additive in a larger amount and at least one is a toner containing the large diameter external additive in a smaller amount, in which the primary particle diameter of the large diameter external additive is from 150 nm to 2,000 nm, the content of the large diameter external additive in the toner containing the large diameter external additive in larger amount is from 0.06% by weight to 4.0% by weight and the content of the large diameter external additive in the toner containing the large diameter external additive in the smaller amount is not more than 0.05% by weight.
