    摘要： A carrier for electrophotographic developer comprising carrier particles, each carrier particle having at least one surface-coating layer of resin material, characterized by the surface-coating layer containing an acrylic resin and a silicone resin, the acrylic resin being in an amount of from 10 to 90 wt. % based on the total amount of resin coating ingredients. The carrier shows no accumulation of toner-spents, therefore can obtain a stable electric charge, and has no layer scraping in binder resin layer, therefore can obtain a stable electric resistance, hence occurs no deterioration of images reproduced, by using acrylic resin having high anti-abrasive and high surface energy, whereas it has strong adhesiveness and high fragility, in combination with use of a silicone resin having poor anti-abrasive and small adhesiveness but has low fragility, thus is hard to cause a toner spent and hard to integrate the spent constituents due to its low surface energy.
