Abstract
An image forming method includes: charging a surface of an electrostatic latent image holder with a charging roller; exposing the charged surface so as to form an electrostatic latent image; and developing the formed electrostatic latent image with toner. The toner contains at least a toner base particle and an external additive minute particle. The external additive minute particle contains a silica-polymer composite minute particle. A silicon atom abundance ratio obtained from abundances of a carbon atom, an oxygen atom and a silicon atom present on an outermost surface and within 3 nm from the outermost surface in a depth direction of the silica-polymer composite minute particle are measured with an x-ray photoelectron spectrometer satisfies at least the following condition A.
