PURPOSE:To execute stably high-speed copying by adding wax particles to toner particles as a one-component magnetic toner, and bringing then into press contact with an elastic rubber blade as a cleaning mechanism and providing a mechanism for rubbing it along the longitudinal direction. CONSTITUTION:This one-component magnetic toner is formed by adding wax particles to toner particles which have dispersed a magnetic material particles into a fixing medium in a quantity ratio of 0.1-0.3wt% per toner particle. The wax particles are used by limiting the quantity to be used within a prescribed range, and also in case when a mechanism for thrusting a blade itself over the longitudinal direction of a supporting body drum is adopted as a blade cleaning mechanism, it is prevented that the surface of the supporting body is damaged due to intrusion of the magnetic toner, by utilizing reversely adhering phenomena of the wax particles, and filming can be prevented effectively. Also, a tip part edge 6 of a blade 3 abuts on a latent image supporting body 7, and by using the shaft core of a shaft 2 as the rotation center, a prescribed force is applied to a latent image supporting body by an angular moment generated by a weight 5.
