ABSTRACT:
On surfaces of insulating layers1band1cof a transportation member1, a protective layer1dhaving a volume resistivity of 1010Ω·cm to 1017Ω·cm is so laminated that a sum of thickness of the insulating layers1band1cis less than intervals between adjacent ones of progressive wave generating electrodes2. With this arrangement, it is ensured that a progressive wave electric field generated by the progressive wave generating electrodes2is exposed beyond a surface of the transportation member1. Even if developer T and the transportation member1contact each other, a surface potential of the transportation member1is not changed. Moreover, firm adhering of the toner T to the surface of the transportation member1is prevented. It is therefore possible to certainly transport the developer T to a development position always stably.
