Abstract
In an image forming apparatus, an AC bias is supplied to a conveyance belt, and the amount of charge on the printing side of a recording sheet is decreased. The charge of positive polarity and the charge of negative polarity which are different from each other are generated on the printing side of the sheet, so that both the charges are cancelled by each other and the charge on the printing side of the sheet is eliminated. Moreover, the charge eliminator eliminates the charge on the printing side of the sheet by the time the sheet is electrostatically attached to the conveyance belt and conveyed to a position where the sheet confronts the head.
