Abstract
The present invention provides a non-contact ink developing method for developing an electrostatic latent image formed on an electrostatic latent image formation member with ink, characterized by employing a conductive ink as the ink and a conductive developing roller disposed close to the electrostatic latent image formation member and whose surface has a water-repellent finish for producing very small ink droplets which are substantially spherical. The method comprising the steps of supplying the conductive ink to the surface of the conductive roller to produce a large number of very small ink droplets, and ejecting the ink droplets toward the electrostatic latent image in a developing area facing the electrostatic latent image formation member by an electrostatic induction force generated by charges of the electrostatic latent image and charges of opposite polarity induced in the ink droplets by the electrostatic latent image, and attaching the droplets to the electrostatic latent image.
