Abstract
A transport device for use in a recording apparatus is disclosed. The transport device includes a conveyor belt having at least three layers. The upper layer of the belt is a conductive or semiconductive layer that is discriminable from a recording material by a detector. Below the first conductive or semiconductive layer is an insulating layer and below the insulating layer is a third conductive layer. The first layer has a volume resistivity value of from 10.sup.14 to 10.sup.17 .OMEGA.cm. The detectors are positioned upstream and downstream of the recording region and disposed downstream of that recording region is a cleaning blade and absorber which together work under control of a controller to clean ink from the conveyor before it soils the charging roller or the next recording sheet. The controller also controls the cleaning operation in accordance with the amount of ink that was unnecessarily jetted onto the conveyor belt.
