Patent ID: 8251506

Claim:
An ink jet recording apparatus, comprising: an inkjet head in which is formed an ejection surface through which ink is ejected; a conveyor mechanism which includes: a conveyor belt having a conveyor surface that is opposed the ejection surface; and a belt drive mechanism configured to move the conveyor belt and which is configured to convey a recording medium on the conveyor surface in a medium conveyance direction in which the recording medium is conveyed; a pair of comb electrodes which are disposed so as to be opposed to the ejection surface with the conveyor surface interposed therebetween, each of the comb electrodes including a plurality of electrode portions that are arranged in a direction perpendicular to a direction in which the comb electrodes are opposed to the ejection surface, each of the plurality of electrode portions of one of the comb electrodes and each of the plurality of electrode portions of the other of the comb electrodes being alternately arranged in the direction in which the plurality of electrode portions of each of the comb electrodes are arranged; a voltage-application power source configured to apply a voltage between the pair of comb electrodes; and a controller which has an attraction control portion configured to control the voltage-application power source so as to attract the recording medium to the conveyor surface and which controls operations of the ink jet recording apparatus, wherein the attraction control portion is configured to control the voltage-application power source such that the voltage is applied between the pair of comb electrodes after initiation of the movement of the conveyor belt by the belt drive mechanism, and wherein the attraction control portion is configured to control the voltage-application power source such that the voltage is applied between the pair of comb electrodes before initiation of the movement of the conveyor belt by the belt drive mechanism, for eliminating electric charge remaining on the conveyor belt.
