ABSTRACT:
An electrostatic type ink jet printing apparatus, wherein a charger activated by a direct current source is disposed close to the surface of the recording paper conveying drum or belt in order to charge the surface of the drum or belt inversely to the polarity of charge on charged ink drops. On that occasion, charged areas may be intermittently disposed on the recording paper conveying drum or belt. Moreover, the recording paper is tightly and electrostatically fixed on the recording paper conveying drum or belt, so that the charged condition on the surface of the recording paper is kept stable and therefore formation of high quality printed image may be realized regardless to the environmental circumstance related, for instance, to humidity, electric field, and the like.
