摘要:
A disclosed fixing device applying a bubble-like fixing liquid to resin-containing particles adhered to a medium so that the resin-containing particles are fixed to the medium, the bubble-like fixing liquid being formed by transforming a fixing liquid into foam that dissolves or swells at least a part of the resin, includes a control device that, based on a difference between a moisture content included in the medium after fixing and a target value of the moisture content, adjusts an application amount of the fixing liquid for a next medium.

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:
A device for supplying a liquid developer from a toner container to a tank and from the tank to a developing unit of which is operable with the liquid developer. The nozzle hole of the toner container is open into a circulation path along which the liquid developer is circulated. Hence, the nozzle hole is constantly dipped in the liquid developer without regard to the liquid level in the tank and, therefore, is free from the deposition of dried toner particles.

A disclosed cleaning device for removing adhering matter from a surface of a member subject to cleaning includes a belt-shaped film member arranged in a stretched configuration capable of being wound or endlessly move in a direction opposite to a surface movement direction of the member subject to cleaning while being in contact with the surface of the member subject to cleaning, and a cleaning blade configured to abut on the surface of the member subject to cleaning via the belt-shaped film member at a position where the belt-shaped film member is brought into contact with the member subject to cleaning.
摘要:
A fixing apparatus causes a softener to adhere to a toner image and then fixes the toner image onto a recording body. The toner image is formed using a liquid developer comprising a toner and carrier solution. The fixing apparatus comprises a fixing roller as a softener feeding device for feeding a fixer containing a softener to a transfer paper which is a recording body, and a pressurizing roller as a pressurizing device for pressurizing the transfer paper at a fixing nip which is a softener feeding position to which the fixer is fed. As the softener contained in the fixer, the one having an affinity for the carrier solution is used.

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:
A cleaning device for use in an electrophotographic copier, facsimile apparatus or similar image recorder for cleaning a photoconductive element to remove a toner which remains on the photoconductive element after image transfer. If the temperature of the photoconductive element is lower than 35 degrees centigrade, a cleaning blade is held in pressing contact with the photoconductive element after an image recording operation. If the temperature is 35 degrees centigrade or higher, the blade is released from the photoconductive element upon the lapse of a predetermined period of time after a copying operation.
摘要:
An improved high-tension capacitor is proposed which uses no insulation oil or gas. Not only the dielectric layers in the capacitor elements are impregnated with synthetic resin, but also the capacitor elements are insulated with synthetic resin by impregnating the insulation material around the capacitor elements with synthetic resin. The insulating layer around the capacitor elements is formed with a plurality of air ducts.
摘要:
A fixing device for applying a foam fixing agent to particles including resin resting on a medium to fix the particles including resin onto the medium. The foam fixing agent includes a softener for softening the particles including resin by dissolving or swelling at least part of the resin. The fixing device includes a first foam fixing agent generating unit that generates a first foam fixing agent from a fixing agent; a second foam fixing agent generating unit that generates a second foam fixing agent from the fixing agent, the second foam fixing agent having a lower density than the first foam fixing agent; and a foam application member on which a first film formed with the first foam fixing agent and a second film formed with the second foam fixing agent are formed.
