Abstract (en)

The developing method of the invention is a developing method in which a two component type developer layer comprising toners and carriers is formed on a developer transport drum and the formed developer layer is fed into a developing area where an oscillatory electric field is generated so as to develop an electrostatic latent image on a photoreceptor. The carrier is a resin coated carrier being a particle of magnetic substance coated with a resin containing silicone resin or a resin containing fluororesin in an amount of at least 30 % by weight.
