摘要：
Disclosed is a carrier of a developer, which is characterized in that the current value observed when a direct current is applied under a voltage of 200 V is 0.8 to 2.0 .mu.A and the relaxation time is in the range of from 4.0 to 6.0 milliseconds, that is, the characteristic values in the dynamic state, for example, in a developing apparatus, are kept with certain ranges. If this developer carrier is used, an image having a high quality can be obtained without occurrence of troubles often caused in conventional developers, such as carrier dragging (transfer of the carrier to a photosensitive material together with the toner), fogging (transfer of the toner to the background of a copying sheet) and letter thinning.
