CARRIER FOR ELECTROPHOTOGRAPHY

摘要

PROBLEM TO BE SOLVED: To provide a carrier which prevents peeling of the resin coat of a carrier for electrophotography and achieves a long service life. SOLUTION: The carrier for electrophotography has A% (A<=40) of an air hole coefficient on a core particle surface and B% of coverage of an air hole part on the core particle surface with a resin coat, satisfies A×B/100>=15 and has a coverage of <=20% of a flat and smooth part except the air hole part on the core particle surface with the resin coat.
