SOLUTION: This device is constituted that an elastic blade 7 and an elastic roller 6 is severally held in contact with the developing sleeve 5. the elastic blade 7 is provided with a rubber elastic layer 16 held in contact with a nip part of the developing sleeve 5 and the metallic conductive thin layer 17 supporting the rubber elastic layer from the rear side. An electric power source 18 is connected to the conductive layer 17, and the alternating electric field provided with the symmetrical waveform so as to make the average electric field becomes to 0 is formed, between the conductive layer 17 and the developing sleeve 5.  Thus, the toner is allowed to cause shuttle movement between the elastic blade 7 and the developing sleeve 5, therefore the toner 8 flocculating at the time being sent to a controlling part of the elastic blade 7 by the elastic roller 6 is allowed to disentangle. As a result, the toner thin layer can be formed in an always stabilized state, therefore the toner is prevented from dripping in drops.
