PURPOSE:To effectively clean up the surface of a photosensitive body without damaging it and to obtain an electrostatic charge image developing toner with stabilized frictional electrification property by using composite particulates obtained by coating the surfaces of resin particulates with an iron oxide group magnetic substance. CONSTITUTION:Colored particulates consisting of binder resin and a coloring agent and composite particulates obtained by coating the surfaces of resin particulates with the iron oxide magnetic substance are contained in the toner. In such configuration, the abrasive property of the composite particulates can be appropriately set up and the adhesion of composite particulates to the colored particulates can be improved. Since appropriate abrasive property can be displayed without damaging the surface of the photosensitive body, effective cleaning property can be displayed, and because frictional electrification property is stabilized for a long period, an effective image having high image density can be stably formed without generating fogging. |
