Abstract
The invention relates to a carrier and method of making a carrier in which elementary resin particles of volume average particle size not more than 0.5 m are fused on their surfaces to form secondary particles of BET surface areas of 5 to 150 m/g and volume average particle size of 1.5 to 5.0 m, which secondary particles are coated by a dry method on core particles to form carrier particles.
