ABSTRACT:
A toner supply apparatus6is configured to be able to supply a charged toner T to a latent image forming surface LS of a photoconductor drum3. The toner supply apparatus6houses a toner electric field transport body62. The toner electric field transport body62has first portions and second portions which differ in toner T transport force. The first portions and the second portions differ in structural feature, such as relative dielectric constant or thickness. By means of such a structural difference, the state of transport of the toner T on the toner transport surface TTS is appropriately set.
