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.
