ABSTRACT:
In an imaging station of a photocopier, a transfer device is provided in configuration with a photosensitive drum 7. The transfer device is provided with a discharge wire 24 located opposite the photosensitive drum 7, a housing 26, a charge removing member 51, and a shield frame 25. The housing 26 has a pair of insulating blocks 40 supporting either end of discharge wire 24, and a connecting shank 41 formed integrally with and extending between the pair of insulating blocks. The charge removing member 51 is fitted to the shank 41 and removes image-transferring electrical charge from the reverse side of a sheet passed by a sheet supply transport device 15 through the imaging station. The shield frame 25 is formed to at least partially surround the discharge wire 24, and has an opening 30a on the side facing photosensitive drum 7, into which support housing 26 is fitted.
