摘要： A solid-concentration measuring apparatus includes an ultrasonic transmitter, an ultrasonic receiver, and a response-time integrator. The ultrasonic transmitter transmits a single-pulse ultrasonic wave to a liquid toner. The ultrasonic receiver receives the single-pulse ultrasonic wave. The ultrasonic transmitter transmits again a single-pulse ultrasonic wave after a predetermined time has passed from when the ultrasonic receiver receives the single-pulse ultrasonic wave. The response-time integrator measures a response time from transmission to reception of each single-pulse ultrasonic wave, and integrates the response time with respect to each set of N pulses (N>1). A solid concentration of the liquid toner is calculated based on the integrated response time.

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 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： Document image data is converted into luminance image data. Block image data is generated from the luminance image data. Start point block pixel data and end point block pixel data are set based on a change rate of luminance values of adjacent block pixel data. A luminance value of block pixel data between the start point block pixel data and the end point block pixel data is corrected based on a start point luminance value and an end point luminance value. The luminance value, of the block pixel data wherein each luminance value of an adjacent block pixel data cluster is less than an average value, is substituted by the average value. The luminance value of each pixel data is set based on the luminance value of the block pixel data. Post process luminance image data that includes each pixel data is reconverted into the document image data.
