摘要： A liquid-development electrophotographic apparatus forms on a toner-image-bearing body a plurality of color images developed by a plurality of developing units, one for each color, that use liquid toner. One or more carrier-removing units for removing excessive carrier from a toner layer that forms a toner image are disposed downstream of each developing unit and upstream of the next developing unit disposed upstream of the former developing unit with respect to a process progress direction. Each carrier-removing unit includes two or more conductive collection rollers to which a bias voltage is applied in such a direction as to press toner against the toner-image-bearing body and which is brought into contact with the toner-image-bearing body. The upstream roller is rotated in the same direction as the direction of surface movement of the toner-image-bearing body, whereas the downstream roller is rotated in the opposite direction. The result is that influence of carrier on the already transferred image is suppressed, and hence occurrences of irregular transfer of the images and occurrences of disturbance of the already transferred image are minimized.

摘要： An electrode module in the form of a flexible sheet which contacts with a toner layer and to which a bias voltage is applied is provided on a developing roller before development. The electrode module is adapted to separate the toner layer largely into a toner-rich layer and a carrier-rich layer by utilizing electrical migration occurring in the toner layer when an electric field is applied to the toner layer on the basis of the bias voltage. The electrode module is constructed in such a manner that the sheet is pulled toward a surface of the developer bearer body by a force attributable to surface tension or wetting characteristic of the liquid developer existing between the sheet and the developer carrying body, whereby the sheet comes into contact with the surface of the developer bearer body. This electrode construction increases the contact area or nip width of a bias blade provided for the developing roller and enhances its contact stability.

摘要： A liquid-development full-color electrophotographic apparatus utilizes a development section having a liquid toner as a liquid developer to form a toner image according to an electric field established between the development section and a photosensitive drum. The toner image is transferred from the photosensitive drum onto an intermediate transfer roller according to an electric field established between the intermediate transfer roller and the photosensitive drum, from the intermediate transfer roller to an intermediate transfer belt, and then to a transfer-and-fixation section, which melt-transfers the toner image onto a printing medium. A voltage controlled according to electric characteristics of each color toner is applied to the corresponding photosensitive drums while the roller is grounded. A toner cohesion enhancement unit is provided for enhancing the degree of toner cohesion of a toner image transferred and reverse transfer is suppressed.

摘要： Provided are an applicator roller for conveying and applying liquid toner onto a developing roller in the form of a level, thin layer, and a conductive blade which comes into contact with a liquid toner layer on the developing roller. A predetermined amount of liquid toner passes through a gap between the conductive blade and the developer roller; and voltage is applied to the conductive blade so as to establish a state such that toner particles contained in the liquid toner are sparsely scattered in a surface region of a level, thin toner layer on the developing roller. Subsequently, the liquid toner, whose surface region is in a state such that toner particles are sparsely scattered, is brought into contact with an image bearer body for performing development.

摘要： The present invention provides a toner recycling control system which stably feeds a liquid developer of an appropriate concentration to a liquid developing apparatus employing a high-viscosity liquid developer; appropriately adjusts the concentration of residual developer collected after development and after transfer; and feeds the adjusted developer to the developing apparatus. The toner recycling control system collects a post-development residual developer from a developer-bearing body and a post-transfer residual developer from an image-bearing body; performs developer concentration adjustment to yield an adjusted developer; and feeds the adjusted developer back to the developer-bearing body. Thus, the toner recycling control system includes a concentration adjustment tank which stores the collected developer and is replenished with a concentrated developer and carrier liquid for developer concentration adjustment; and a buffer tank which receives and stores a liquid developer which has undergone concentration adjustment in the concentration adjustment tank. Once adjusted to an appropriate concentration, the liquid developer is fed to the developer-bearing body from the buffer tank.

摘要： A semiconductor pressure converter wherein a drive voltage is applied to a power supply end of a shearing type gage formed at the strain generating part of a semiconductor diaphragm, and an output voltage appearing at the output end thereof is amplified with an amplifier. The zero point is adjusted by applying a bias voltage to the amplifier which is related to the drive voltage. The span is adjusted without interference to the zero point by changing the feedback voltage of the amplifier. Linear compensation, temperature zero point compensation and temperature span compensation are attained without any mutual interference.
