<p>A carrier for electrophotography is constituted by magnetic carrier core particles and a resin coating layer coating the magnetic carrier core particles. The carrier core particles contain a magnetic ferrite component represented by the following formula (I): (Fe2O3)x(A)y(B)z wherein A denotes a member selected from the group consisting of MgO, AgO and mixtures thereof; B denotes a member selected from the group consisting of Li2O, MnO, CaO, SrO, Al2O3, SiO2 and mixtures thereof; and x, y and z are numbers representing weight ratios and satisfying the relation of: 0.2 </= x </= 0.95, 0.005 </= y </= 0.3, 0 < z </= 0.795, and x+y+z </= 1. The coated carrier particles thus formed exhibit excellent performances in continuous image formation. <IMAGE></p> |
