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.

A developing unit for visualizing an electrostatic latent image formed on a photoreceptor drum with a toner, includes: a hopper for storing a developer; a developing roller for supplying the toner to a photoreceptor drum on which an electrostatic latent image is formed; and an agitating and conveying portion. In the developing unit, the agitating and conveying portion includes first and second agitating and conveying belts, each having toner agitating blades for agitating and conveying the toner. The first and second agitating and conveying belts are rotatably arranged in the hopper with their rotational axes set approximately vertically so as to rotate the toner agitating blades approximately horizontally.

In a die bonding apparatus with a position correcting stage that has a die carrying surface upon which a die is placed by a collet, the external circumferential shape of the die carrying surface of the position correcting stage is formed so as to be smaller than the external circumferential shape of the die to be carried on the die carrying surface, thus avoiding damages to the surface of the die.
