ABSTRACT:
A charge removing member is arranged just upstream of an image transfer area along a continuous form transport path, between the last guiding portion and the transfer area, to remove accumulated charge on the continuous form. The charge removing member is alternatively a brush contactable to the form, a non-contact conductive member, a brush movable toward and away from the form, or a brush that acts as a guide member. Further alternatively, the brush contacts the form only during reverse feeding of the form, and in this case, is alternatively movable toward and away from the form, movable toward and away from the form in association with a transfer unit, or positioned to contact a straight form while being out of contact with a form bent by a transfer unit.
