ELECTROSTATIC LATENT IMAGE DEVELOPING CARRIER AND DEVELOPER USING SAME

摘要

PROBLEM TO BE SOLVED: To provide an electrostatic latent image developing carrier capable of imparting stable electrostatic chargeability to a toner even at high temperature and high humidity and at low temperature and low humidity over a long period of time. SOLUTION: The electrostatic latent image developing carrier has core particles 30 of a magnetic material and a coating layer 20 containing a matrix resin 21, fine resin particles 22 and an electrically conductive fine powder 23 on each of the core particles 30. The volume average particle diameter of the electrically conductive fine powder 23 is <=0.5μm and the value X represented by the expression X=(the 80% integrated diameter of the electrically conductive fine powder)/(the volume average particle diameter of the electrically conductive fine powder) is 1.00-2.00. The electrically conductive fine powder preferably comprises a metal oxide.
