Abstract
An inkjet printer includes a movable conveyance belt, a first charging device, and a second charging device. Upon the conveyance belt, a recording medium is placed and conveyed at a given conveyance speed in a longitudinal, conveyance direction of the belt. The first charging device is disposed in contact with the belt while supplied with a first alternating current voltage to create a first electrified portion in the conveyance belt where positive and negative electric charges are arranged alternately with each other in the conveyance direction for electrostatically attracting the recording medium to the belt. The second charging device is disposed adjacent the belt to contact the recording medium conveyed on the belt while supplied with a second alternating current voltage to create a second electrified portion in the recording medium for cancelling an electric field originating from the first electrified portion of the belt.
