Abstract

PURPOSE:To enable good images to be stably formed in numerous times by using a toner comprising a binder resin powder and fine resin particles smaller than said powder in diameter subjected to surface treatment with a fine inorganic material. CONSTITUTION:The toner comprises the binder resin powder and the fine resin particles having a smaller diameter than that of said powder and subjected to surface treatment using the fine inorganic material having a diameter of <=1/2 that of said fine resin particles, preferably, obtained by mixing the fine resin particles having an average particle diameter of 0.05-3mum with the fine inorganic material and giving mechanical impact to them to fix said material to the surface of each of the fine particles, thus permitting good images to be stably formed in numerous times, not accompanied by damage of a photosensitive body and stains with the toner constituents.
