摘要： Whether or not a density of black is a predetermined value or more is judged, and when it is judged to be the predetermined value or more, a resolution characteristic is changed to an improved resolution characteristic compared to the resolution characteristic used in a case in which a judgment result shows a value under the predetermined value. When the density of black is deeper, the resolution characteristic is improved, and therefore black is prevented from becoming in a so-called void state. Accordingly, the color close to black such as four-color black can be stably and excellently formed. In addition, when the density of black is the value under the predetermined value, the resolution characteristic lower than this value is used, and therefore dots can be stably formed and an excellent gradation property can be achieved.

摘要： An apparatus for forming a multi-color is disclosed which includes a controller that performs an anti reverse-transfer control such that a surface potential of a previously-formed separated-developer-image subset of a plurality of single-color separated-developer-images which has been previously transferred onto an image transferred medium is reduced, prior to a subsequent transfer in which a remainder of the plurality of separated-developer-images is transferred onto the image transferred medium after a previous transfer of the previously-formed separated developer-image subset onto the image transferred medium, to thereby prevent a reverse transfer of a part of a developer material on the image transferred medium from the image transferred medium onto a photoconductor at the subsequent transfer.

摘要： A control section sets the transfer bias level applied between a transfer roller and a photosensitive drum in the printer to a “ghost generation level.” The control section forms a test pattern on the recording medium by applying a transfer bias set to the ghost generation level in order to transfer a toner image onto the recording medium. A density sensor detects the density of the toner image deposited in a non-image-forming region when the test pattern is formed. The control section estimates a transfer bias level, at which ghosts will not occur, based on the ghost generation level and the density level of the toner image in the non-image-forming region, and sets this estimated value as the transfer bias level for forming images.

摘要： A pressure sensor 16 has a length C and a width D identical respectively to a length A and a width B of a fluid pumping section 11 and is provided in a portion of a cover 15 opposite to the fluid pumping section 11. The fluid pumping section 11 has a structure for pressing a tube placed in a groove 13 by means of fingers which advance and retract in a cavity 14 formed in a wall 12 of a main body. A possible erroneous placement of the tube is detected according to a change of pressure force exerted from each of the fingers, detected by the pressure sensor 16 . The pressure sensor 16, which is provided within a range in which the fingers can press the tube, can detect even a slight displacement, of the tube from the range in which the fingers can press the tube, to thereby allow detection of erroneous tube placement free of a dead zone to be achieved.
