<P>PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing carrier giving an image which ensures little fogging and suppresses void generation phenomenon in a gradation boundary region. <P>SOLUTION: The electrostatic charge image developing carrier comprises a ferrite core material and a resin coating layer to coat the core material. The carrier in the form of a magnetic brush has a volume resistivity of 10<SP>13.7</SP>-10<SP>17</SP>Ωcm under an electric field of 4,000 V/cm and a volume resistivity of 10<SP>6</SP>-10<SP>9</SP>Ωcm under an electric field of 15,000 V/cm. <P>COPYRIGHT: (C)2011,JPO&INPIT |
