摘要： To suppress a change in toner density in a liquid developer when forming an image, the available amount of toner is controlled be it on a developer roller (31) or an image carrier in accordance with a control signal received from a CPU. Any one of squeegee rollers (51,52,53) or the developer roller (31) selectively moves into and out of contact with a developer carrying surface, or is independently switched to various power sources via bias generators (119) to adjust toner and/or carrier consumption.

摘要： As an urging member urges a front surface side roller (480) against a back surface side roller (45), the front surface side roller (480) and the back surface side roller (45) bring an intermediate transfer belt (41) and a recording medium (4) into pressure contact with each other at a secondary transfer position (490). The thermal capacity per unit surface area of each one of the front surface side roller (480) and the back surface side roller (45) is larger than the thermal capacity per unit surface area of the intermediate transfer belt (41) to suppress a temperature hike to below the boiling point of water. Further, the thermal capacity per unit surface area of the back surface side roller (45) is larger than the thermal capacity per unit surface area of the front surface side roller (480) to suppress a reduction in water content of the recording medium (4).

摘要： A developing device includes a supply member (3) disposed to rotate in contact with a developer carrier (4) to supply a developer layer having a predetermined thickness to the developer carrier surface. A layer forming member (2) is disposed to abut against the developer carrier to regulate the layer thickness of the developer so as to form a thin developer layer on the developer carrier. A bias application unit (5,6) applies an AC-superimposed bias voltage to the developer carrier. The AC-superimposed bias voltage is formed by superimposing an alternating current on a DC bias voltage. A latent image on a latent image carrier is developed with the thin developer layer formed on the developer carrier by the layer forming member. The bias application unit sets a maximum value of the AC-superimposed bias voltage lower than the charge potential of the latent image carrier, and sets the DC bias voltage lower than the middle between the charge and exposure potentials of the latent image carrier. The minimum value of the AC-superimposed bias voltage may be set lower than the exposure potential of the latent image carrier. The maximum and minimum values of the AC-superimposed bias voltage may be set so as to be identical in polarity with each other.

摘要： A CPU 113 executes a control program stored in a memory 116 thereby forming a plurality of patch images with a developing bias increased for each of the patch images; detecting a density of each of the patch images by means of a patch sensor 17; and comparing the image densities to determine whether the image density is saturated or not. Then, an image forming condition in which an image density is substantially saturated is determined and is stored in the memory 116. When a print command signal is inputted from an external device via a main controller 100, a printing operation is performed under the image forming condition stored in the memory 116.

摘要： A CPU (113) executes a control program stored in a memory (116), whereby a patch image is formed on a photosensitive member of a photosensitive member unit (10), a light emitter (171) irradiates light upon the patch image, a light receiver (172) receives light from the patch image, whether a received-light signal from the light receiver (172) is within a tolerable range is determined, and an image forming condition is controlled and stored in the memory (116) when the received-light signal is outside the tolerable range. Upon entry of a print instruction signal from an external apparatus via a main controller (100), a printing operation is executed under the image forming condition stored in the memory (116).
