摘要:
An ink jet recording apparatus performing recording by discharging ink from a recording head onto a recording medium. A conveying belt for conveys the recording medium by the attraction of static electricity, an electrode contacts the recording medium conveyed by the conveying belt, and a power source charges the electrode with a charge having a polarity opposite to a charge carried by the conveying belt. The recording head includes a discharge port and a control electrode formed around the discharge port. A voltage identical to the polarity of the surface potential of the recording medium is generated by a power source and applied to the control electrode to cause the control electrode to repel any satellite droplet of the polarity identical to the voltage that splits from a discharged ink droplet during the flight thereof.
