ABSTRACT:
A developing method, which comprises arranging a latent image-bearing member which bears a latent image on the surface and a toner-carrying member which carries an insulating non-magnetic toner at the developing section with a certain gap provided therebetween, coating the toner-carrying member with the insulating non-magnetic toner, conveying the resultant coated layer to the developing section while regulating the thickness thinner than said gap and developing the latent image on the latent image-bearing member under the application of an alternate electric field on the toner. Since the toner has a form of a microcapsule comprising a soft core material and a hard shell material and also contains a colorant in addition to the core material, adequate discharging can be effected during triboelectric charging to give an image with a constant density through stably charged state.
