PURPOSE:To improve the electrostatic charge preservability of a carrier containing florin-incorporated resin coating material, to prevent the sticking of carrier, to enable applying to a developer having a high quality for an organic photosensitive body and reversal development in an inorganic photosensitive body and to efficiently produce the electrostatic charge image developing carrier. CONSTITUTION:In the electrostatic charge image developing carrier coating nucleus particles with resin, florin-incorporated resin having a softing point lower than 150 deg.C and a second resin having a softing point lower over 30 deg.C than the florin-incorporated resin are used as a corting resin. They are mixed with the nucleus particles in a drying condition. Then the coating resin is melted by heating to coat the nucleus particles. |
