Abstract:
1. A charging device that electrically charges a charged object charged while being moved in a predetermined direction comprising: a charging member that electrically charges the charged object; a power source adapted to supply the charging member with an electric power showing a voltage waveform obtained by superimposing an AC voltage on a DC voltage; a contact member arranged downstream relative to the charging member as viewed in the moving direction of the charged object and adapted to contact the charged object directly or by way of a predetermined intermediary medium; an ammeter that gauges an electric current caused to flow through the contact member due to an electric charge on the charged object electrically charged by the charging member; and a power source control section adapted to control the electric current of the AC component supplied to the charging member by the power source on the basis of the electric current gauged by the ammeter.
