Abstract (en)
A carrier for a developer which satisfies the following relation: 1.7 </= X/Y </= 3.3 wherein X is the resistivity ( OMEGA .cm) of the carrier in a compressed state to which a DC voltage of 1000 V is applied, and Y is the resistivity ( OMEGA .cm) of the carrier in a state in which the carrier particles are linked together in a chain form in a magnetic field of 1600 gauss to which a DC voltage of 1000 V is applied, thereby constantly providing satisfactory developing characteristics regardless of variations in copying conditions.
