ABSTRACT:
An electrophotographic two-component type developer includes a toner and a magnetic carrier showing stable charge-imparting performances for a long period of continuous image formation and wherein various environmental conditions. The magnetic carrier comprises: magnetic carrier core particles and a silicone resin coating the magnetic carrier core particles; wherein the silicone resin is characterized by having (i) both (a) a --COO-- group and (b) a phenyl group or nitrogen-containing group, (ii) a carbon content attributable to the --COO-- group of 10-70 atomic % of silicon constituting the silicone resin, based on ESCA, and (iii) a carbon content attributable to the phenyl group of 0.1-300 atomic % or a nitrogen content attributable to the nitrogen-containing group of 0.01-10 atomic %, respectively, of the carbon content attributable to the --COO-- group, based on ESCA.
