摘要： Featured is an imaging forming apparatus that provides minute particles having a uniform diameter and being uniformly charged. The image forming apparatus includes a supplying member that supplies charged developing particles, a counter electrode disposed opposite to the supplying member and a control electrode disposed therebetween and including a plurality of passing holes serving as passages for the developing particles. While a potential for generating a predetermined potential difference is applied between the supplying member and the counter electrode, the potential being applied to the control electrode is changed in order to change an electric field existing between the supplying member and the counter electrode. This controls flying of the developing particles passing through the passing holes in a direction from the supplying member to the counter electrode, and thus the forming of the image. The developing particles are formed of a liquid or liquescent material, and fine-grained and charged with electricity by the supplying member. The supplying member is particularly configured or arranged so the developing particles thereon formed have a diameter to minimize particle fragmentation during flying from the supplying member towards the control electrode.

摘要： An image forming apparatus is provided with a control electrode having a plurality of gates where negatively charged toner passes through, and the control electrode is arranged such that an electrode layer is formed on an insulating layer made of synthetic resin having electron attractiveness stronger than that of synthetic resin contained in the toner. For this reason, on the control electrode, when the toner flies to contact with the insulating layer, electrostatic force (repulsive force) acts between negative charges of the contact portion and the negative charges of the toner, and thus the charges repulse each other. Therefore, the toner does not adhere to the insulating layer. In such a manner, the adhesion of the toner to the control electrode is prevented and thus each gate is not blocked. As a result, even after long or frequent use of the control electrode, the flying of the toner by the control electrode can be stably controlled, thereby making it possible to obtain an image with excellent quality. Therefore, even if the control electrode is not maintained, namely, cleaned or replaced, an image with excellent quality can be obtained stably for a long time.
