<p>PURPOSE: To obtain a carrier and a developer having satisfactory electrostatic charge kick-off characteristics, not causing fogging or scattering over a long period of time, not causing the blurring of an image or defective cleaning, capable of reducing the dependency of electrostatic charge characteristics on the environment and not causing defects such as the blurring of letters at the time of transfer and fixation and to provide a heat fixing method using the developer. CONSTITUTION: In a developer consisting of at least a carrier with resin coating layers on the surfaces of magnetic particles and a toner, at least an Mg compd. represented by the formula Mg(X)n n [where X is O, CO3 or OH and (n) is an integer of 1 or 2] and inorg. oxide of an element belonging to the group IIb, IIIa, IIIb, IVa or IVb of the Periodic Table are incorporated into the resin coating layers and the objective electrostatic charge image developer is obtd.</p> |
