摘要： In an image forming apparatus, a developing device includes a reservoir storing a viscous and dense developing liquid. A developing sleeve, an applicator roller, a circulation pump for circulating the liquid and a screw for agitating the liquid are disposed in the reservoir. The reservoir is open only at its portion where the developing sleeve contacts an image carrier. The liquid is agitated by the screw before flowing into the circulation pump and then applied to the applicator roller. As a result, the liquid is fed to the developing sleeve via the applicator roller with a uniform toner content. The apparatus is small size and stably forms high quality images.

摘要： An image forming apparatus and a developing device that can deposit a developing liquid on a liquid carrier in a form of a thin layer, causing the thin layer to contact an image carrier of the image forming apparatus. A liquid carrier is in contact with the image carrier to carry the thin layer of the developing liquid to the image carrier. A thin layer contact member contacts the thin layer formed on the liquid carrier at a position upstream of where the liquid carrier and the image carrier contact each other in a direction in which the liquid carrier is movable, to apply a shearing force to the thin layer. Further, the thin layer contact member includes a rotary member with a movable surface that rotates, at a position where the rotary member faces the liquid carrier, in a rotating direction opposite to the rotation direction in which the liquid carrier is movable.

摘要： An image forming apparatus, a developing device and a program recording medium capable of reducing short image density, background contamination and short image sharpness ascribable to the use of a developing liquid whose viscosity characteristic is dependent on a shearing force. Before an applicator roller included in a developing device starts rotating for developing a latent image formed on a photoconductive drum, screws disposed in a liquid storing portion start rotating.

摘要： An image forming apparatus suppresses several kinds of inconveniences caused by unnecessary contact of a belt-formed member with opposing members and drives the belt-formed member accurately even when the belt-formed member separated from a part of a plurality of opposing members. In an image forming apparatus having a belt-formed member supported by a plurality of supporting rollers and a plurality of opposing members located side by side in a line to oppose and contact the belt-formed member, a pivot mechanism is employed to temporarily separate the belt-formed member from a part of the opposing members for color image formation. The image forming apparatus also includes a tension roller dive mechanism to increase a relative distance between the tension roller and other supporting rollers to suppress a decrease in a tension of the belt-formed member during the above-described separation of the belt-formed member from the plurality of opposing members.

摘要： An image forming apparatus including a plurality of image forming units or process units is disclosed. The process units may each be moved into and out of the body of the apparatus by hand. A plurality of support members for supporting the ends of the process units to be operated by hand extend substantially parallel to a linear path for conveying a recording medium, but outside of paths for moving the process units into and out of the apparatus body. A positioning mechanism positions the above end of the individual process unit relative to the support members. The positioning mechanism is implemented by holes formed in the support members, and pins studded on a positioning wall included in the individual process unit. The apparatus allows the process units to be positioned thereon accurately with a high mechanical strength, while allowing them to be mounted and dismounted with ease.
