PURPOSE:To enhance cleanability and to stably form an image free from black spots by incorporating fine inorganic particles and fine organic particles having an average particle diameter of <=3mum of their primary particles and larger than that of the primary particles of the inorganic particles. CONSTITUTION:The toner comprises, as essential components, binder resin particles, the fine inorganic particles, and the fine organic particles having an average particle diameter of <=3mum of their primary particles and larger than that of the primary particles of the inorganic particles, thus permitting the obtained tone to achieve good cleaning in a state of reduced contact pressure of a cleaning blade to an latent image bearing body, and consequently, to prevent scratching of the surface of said by due to the inorganic particles, and to stably form images free from black spots in a large number of times. |
