    • An apparatus for developing an electrostatic latent image includes a first developing agent application device and a second developing agent application device disposed facing the peripheral surface of a photosensitive material drum, a developing agent stirring/conveying mechanism for conveying the developing agent to the first developing agent application device, a magnetic conveyer disposed at the back of the second developing agent application device, and a developing agent return guide plate for sending the developing agent conveyed by the magnetic conveyer to the side of the developing agent stirring/conveying mechanism. The second developing agent application device is provided with a developing agent-peeling zone where magnetic poles of the same polarity are magnetized neighboring each other on the upstream side of the position which is closest to the sleeve member of the magnetic conveyer in the direction of rotation. The magnetic conveyer has a magnetic pole at a position facing the developing agent-peeling zone. The magnetic pole has a polarity opposite to that of the polarity of the magnetic poles forming the developing agent-peeling zone.
