Abstract:
An image forming apparatus comprising:a supplying means for supplying charged developing particles and including a supplying member;a counter electrode disposed opposite to the supplying member;a control electrode disposed between the supplying member and the counter electrode and having a plurality of passing holes serving as passages for the developing particles;wherein while different potentials are applied to the supplying member and the counter electrode, respectively, to generate a predetermined potential difference therebetween, a potential which is to be applied to the control electrode is changed, in order to change an electric field existing between the supplying member and the counter electrode, to thereby control flying of the developing particles passing through the passing holes in a direction from the supplying member to the counter electrode, thereby forming an images;wherein the developing particles are formed of a liquid or a liquescent material; andwherein the supplying member is configured to charge the developing particles with electricity and to form the developing particles thereon so as to have a desired diameter not more than a predetermined diameter.
