ELECTROSTATIC LATENT IMAGE DEVELOPER AND IMAGE FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electrostatic latent image developer with which high image quality may be obtained for a long period and the high image quality may be maintained in a wide toner density range and an image forming method. SOLUTION: The electrostatic latent image developer characterized in that the carriers of the electrostatic latent image developer containing the carriers and toners are formed by providing amorphous ferrite cores of >=130 in the shape coefficient (SF-1=R2/S×π/4×100) obtained by dividing the square of their maximum length (R) by an area (S) with core layers formed by dispersing conductive powder into a binder resin and that the dynamic electric resistance under an electric field of 104 V/cm ranges from 10 to 1×109Ω.cm and the image forming method.
