Abstract
The present invention provides a magnetic mono-component toner which can suppress a selection development on a latent image carrier and can maintain favorable image properties for a long period by using a toner having the coarse powder distribution (S) within a given range in a jumping developing method and an image forming method which uses the toner. In the toner used in the jumping developing method which develops an electrostatic latent image formed on a latent image carrier using a developer carrier, the toner includes toner particles which contain at least a binding resin and a magnetic powder, and the coarse powder distribution (S) of the toner particles satisfies a following formula (1).Coarse powder distribution ()=(50−)/2≧17 (volume %/μm)  (1)(wherein, A is a volume % of the coarse powder having particle sizes larger than Dbased on volume by 2 μm or more).
