Manufacturing method of electrostatic charge image developing carrier, and manufacturing method of electrostatic charge image developer

Abstract

A manufacturing method of an electrostatic charge image developing carrier, includes a step A in which a mixed solution containing a resin having a glass transition temperature Tg and a solvent is mixed with magnetic particles in a mixer, the mixture is heated to evaporate the solvent to form a resin coating layer on a surface of the magnetic particles so that resin-coated magnetic particles are obtained, and the resin-coated magnetic particles are crushed in a state of being maintained at a temperature TA; a step B in which the resin-coated magnetic particles after the step A are fluidized in a fluidized bed equipment in a state of being maintained at a temperature TB; and a step C in which the resin-coated magnetic particles after the step B are cooled, in which the temperature TA and the temperature TB are each independently equal to or higher than the glass transition temperature Tg−20° C. and equal to or lower than the glass transition temperature Tg+50° C.
