<p>A developing process for two-colored electrophotography comprises: (1) feeding a developer to a non-magnetic sleeve, said developer comprising a first insulative and non-magnetic color toner charged with an electrical polarity, a second insulative and non-magnetic color toner charged with a different polarity from the charging polarity in the first color toner, and a magnetic carrier, (2) holding said developer on the sleeve, (3) transferring the first color toner from the sleeve to a first developing roller to hold on the first developing roller, (4) transferring the first color toner on the first developing roller to an electrostatic latent image on the surface of a photoreceptor with a different polarity from the charging polarity in the first color toner to form a visible image, (5) transferring the second color toner from the sleeve to a second developing roller to hold on the second developing roller, and (6) transferring the second color toner on the second developing roller to the other electrostatic latent image on the surface of the photoreceptor with the other polarity to form a visible image.</p> |
