ELECTROPHOTOGRAPHIC DEVELOPER

摘要

PURPOSE:To obtain an electrophotographic developer capable of attaining high density (high development) and gradation while well maintaining conventional electrostatic charge stability and not causing trouble such as the scattering of a toner or surface fogging because of very high electrostatic chargeability and very high kick-off of electrostatic charge. CONSTITUTION:This electrophotographic developer for developing an electrostatic latent image formed on a photoreceptor contains a toner and an electrostatically chargeable carrier consisting of at least a resin coated carrier obtd. by coating magnetic particles with a resin and 5-50wt.% reduced ferrite particles basing on the amt. of the entire carrier.
