<p>PROBLEM TO BE SOLVED: To provide a color electrophotographic developer freed of image defects, such as deterioration of transfer efficiency, that of image density, that of uniformity, overemphasized edges, void in image, and color stains, especially, even in the case of repeated uses of the full color two-component developer. SOLUTION: The full color electrophotographic developer comprises a carrier having a silicone type resin coated layer on its core material and toner containing an outer additive agent, and this silicone type resin coated toner comprises plural layers, and this outer additive contains at least fine hydrophobic titanium oxide particles treated with a silane coupling agent, this agent being, preferably, alkyltrialkoxysilane represented by CnH2n+1Si(OCmH2m+1)3 in which (n) is an integer of 3-8, and (m) is an integer of 1-3.</p> |
