Title: Binder type carrier and its production
Inventor: TANAKA YOSHIAKI
IPC: G03G9/097
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To produce a binder type carrier not causing the problem of the occurrence of image deficiency and unevenness in density by specifying the relation between the magnetic powder content of a carrier and the amt. of magnetic powder exposed to the surface of the carrier, the shape factor of the carrier and the relation between the volume average particle diameter and number average particle diameter of the carrier. SOLUTION: This binder type carrier has a shape factor of 0.8-0.95 and the ratio (Dv/Dp) of the volume average particle diameter Dv of this carrier to the number average particle diameter Dp is <=1.30. The magnetic powder content of the resin binder is 75-90wt.% and the amt. (b) of magnetic powder exposed to the surface of the carrier and the magnetic powder content a1 satisfy relation represented by the equation b=0.4 (a1 -80)+k1 (where k1 is 4-13wt.%). Since the dispersibility of magnetic powder to the resin binder in a kneaded material is improved, free magnetic powder is less liable to occur in a pulverizing process and the lowering of yield due to classification can be suppressed even in the case of Dv/Dp<=1.30.
