摘要： In a wet-type developing apparatus in which a latent image carrying member and a squeeze roller are moved in the opposite directions to each other while they are not brought into contact with each other at the closest position thereof, a liquid toner layer on the latent image carrying member which is smaller in thickness than the gap interval between the latent image carrying member and the squeeze roller is made to invade into the gap, and the liquid toner invading into the gap between the squeeze roller and the latent image carrying member are brought into contact with the squeeze roller by electrical attractive force based on electric field formed between the squeeze roller and the latent image carrying member, thereby forming meniscus.

摘要： A liquid electrophotographic developing apparatus capable of preventing image drift and reducing the load in the squeezing process. A developing roller faces a photoreceptor belt with a predetermined spacing to supply a liquid developer to the photoreceptor belt while rotating at a peripheral velocity in the opposite direction to that of the photoreceptor belt in a developing region thereon. A peripheral velocity ratio of the peripheral velocity to a moving velocity of the photoreceptor belt is determined so as to maximize a solid component ratio of a developed toner layer on the photoreceptor belt.

摘要： An image forming apparatus of the present invention includes a particle conveying body made up of a light-transmitting conductive layer, an insulative'screen provided on the conductive layer and formed with a number of pores, and a screen electrode formed on the screen. Photoconductive, colored particles are charged to negative polarity and then caused to fill the pores by an electric field. When the particles in the pores are exposed via the conductive layer, electron-hole pairs are generated in the particles. An electric field of as high as 104 V/cm or above is formed between the conductive layer and the screen electrode and separates the electrons and holes. The electrons leak to the conductive layer and cause the particles to be charged to positive polarity. An electric field formed between a facing electrode positioned behind a recording medium and the conductive layer causes the particles to fly toward and deposit on the medium.

摘要： A developing device includes first and second developer carriers facing each other in a facing region, a regulating member that regulates a layer thickness of developer, and a separation member. The first and second developer carriers respectively include first and second magnetic members that are respectively magnetized with first and second facing magnetic poles having opposite polarities. The separation member separates the developer so that the developer is supplied toward the first and second developer carriers. The separation member is disposed such that distances between the separation member and the first and second developer carriers are the smallest in a region in which a magnitude of a combined magnetic field of the first and second magnetic poles locally decreases as compared with a case where at least one of the first and second developer carriers is independently disposed due to interaction between the first and second facing magnetic poles.

摘要： A porous photosensitive unit has a transparent conductive layer formed on a surface of a transparent substrate. A photoconductive layer is formed on a surface of the transparent conductive layer. A porous insulating layer formed on a surface of the photoconductive layer has a plurality of holes for holding conductive color particles. The plurality of holes includes a first hole and the adjacent second and third holes. An upper or screen electrode is formed on a surface of the porous insulating layer except where the holes are formed. The photosensitive unit includes an optical arrangement in which, when a light source emits light to cause conductive color particles to fly out of the first hole only, the light exposes a region, within the photoconductive layer, which substantially coextends with a surface portion of the photoconductive layer that is exposed by the first hole.
