<P>PROBLEM TO BE SOLVED: To provide a carrier for electrostatic charge image development capable of suppressing decrease in resistance of the carrier. <P>SOLUTION: The carrier for electrostatic charge image development comprises a core material, and a cover layer which covers the core material and contains resin and inorganic oxide particles showing conductivity. When the inorganic oxide particles aggregate, an aggregation diameter is equal to or greater than 230 nm and equal to or less than 970 nm, and when the inorganic oxide particles do not aggregate, a primary particle diameter is equal to or greater than 230 nm and equal to or less than 970 nm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
