Ink jet recording apparatus having charged conveying belt

摘要

An ink jet recording apparatus capable of landing an ink drop on an exact position on a recording medium is provided. The ink jet recording apparatus performs recording on a recording medium which has been subjected to application processing with a pretreatment liquid. The ink jet recording apparatus has an electrostatic belt which has a resistance layer formed on the surface thereof, and a power feed roller which imparts charges to the surface of the electrostatic belt. The recording head discharges ink to the surface of the recording medium when the back of the recording medium comes into contact with the surface of the electrostatic belt to which the charges have been imparted.

主权项

1. An ink jet recording apparatus which records on a recording medium having a first face and a second face, the apparatus comprising:
a conveying belt which conveys the recording medium while a surface of the conveying belt contacts the second face; a first DC charge unit which imparts one of positive charges and negative charges to the surface of the conveying belt; a recording head which discharges ink to the first face of the recording medium conveyed by the conveying belt; an application unit which applies a pretreatment liquid to the first face of the recording medium before the second face of the recording medium comes into contact with the surface of the conveying belt to which the charges have been imparted by the first DC charge unit; and a second DC charge unit, provided between the first DC charge unit and the recording head, which imparts a polarity reverse to the charges imparted by the first DC charge unit to the first face of the recording medium to which the pretreatment liquid has been applied.
