Abstract

1448381 Developing process FUJI XEROX CO Ltd 26 Jan 1976 25315/73 Heading G2H In a paddle wheel method of developing an electrostatic latent image formed on an electrophotographic material, there is used, as carrier for the toner, iron powder having on its surface a mixture of Fe 3 O 4 and FeO in such ratio that the ratio of the x-ray diffraction peak of Fe 3 O 4 to FeO is > 1:10 measured according to the method in "Powder Diffraction File", Joint Committee on Powder Diffraction Standards, Philadelphia, U.S.A. No. 11-0614 and 6-0615. Carbon-pigmented acrylic toners are used.
