<p>PURPOSE:To provide a carrier having excellent durability, heat resistance and environmental resistance, not causing toner spending and capable of electrostatically charging a toner in a stable manner. CONSTITUTION:When the core particles of a carrier are coated with a thermosetting resin to produce a thermosetting resin coated carrier for developing an electrostatic charge image, thermosetting resin films are formed on the core particles and subjected to primary baking in the temp. range from the heat curing start temp. to this temp. + 30 deg.C and to secondary baking in the temp. range from a temp. above the primary baking temp. to this temp. + 50 deg.C.</p> |
