摘要：
A detecting coil is placed in the flow of a developer (developing agent) including a magnetic carrier and a coloring toner, which is fed by developer-feeding means. The detecting coil is shaped in a flat plate in a direction perpendicular to the coil axis, which in turn is substantially at right angles to the direction of the flow of the developer.
