发明名称 Magnetic carrier
摘要 A magnetic carrier exhibiting excellent durability against mechanical impact as exerted by vibration and capable of exhibiting a stable charging performance in electrophotography is provided. The magnetic carrier is formed through a process including steps of: surface treating inorganic compound particles with a lipophilizing agent having a functional group (A) selected from epoxy group, amino group, mercapto group, organic acid group, ester group, ketone group, halogenated alkyl group and aldehyde group; forming composite particles from the surface-treated inorganic compound particles and a binder resin; and then surface-coating the composite particles with a coupling agent having a functional group (B) different from the functional group (A) of the lipophilizing agent and selected from epoxy group, amino group and mercapto group, or with a coating resin having a functional group (C) different from the functional group (A) of the lipophilizing agent and selected from epoxy group, amino group, organic acid group, ester group, ketone group and halogenated alkyl group.
