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： 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.
