Abstract

PURPOSE:To provide an apparatus for detecting toner mixing ratio of developing agent for, for example, electronic photographic apparatus, in which there is arranged a detecting element comprising a flat and slender air-core coil on one surface of a developing agent which rotates in a strand to effect detection without interference with the flow of the developing agent.
