摘要： A developing device includes first-third sections, a developing roller, a partitioning wall and a toner concentration detector. The first-third sections have first-third screw augers respectively. The partitioning wall isolates the third section from the first section and the second section. A supply opening is formed in a portion of the partitioning wall opposing the first section. A toner concentration detector is disposed in the third section. The first screw auger conveys developer including toner to the developing roller, into the third section via the supply opening, and into the second section. The second screw auger conveys developer accommodated in the second section into the third section. The third screw auger conveys developer accommodated in the third section into the first section. Toner is replenished into the third section based on a detection result by the toner concentration detector.

Two developing rollers rotating in directions opposite to each other are used, the moving direction of the first developing roller being opposite to the moving direction of the photosensitive body, and a circumferential speed ratio of a circumferential speed of the first developing roller to a circumferential speed of the photosensitive body is within a rage of 0.5 to 2.5; and the moving direction of the second developing roller is equal to the moving direction of the photosensitive body, and a circumferential speed ratio of a circumferential speed of the second developing roller to a circumferential speed of the photosensitive body is within a range of 1.5 to 3.5. A ratio of the sliding friction force between a magnetic brush for developing agent and the photosensitive body formed in the first developing roller and the sliding friction force between a magnetic brush for developing agent and the photosensitive body formed in the second developing roller is within a range of 0.9 to 2.1.

摘要： A rolling contact bearing assembly includes a cage including two or more arcuate members each having a plurality of pockets defined therein for accommodating a corresponding number of rollers arranged consecutively in a circumferential direction to form a ring shaped assembly. The arcuate members are connected together by a retention ring, having an elasticity, over a circumference of the cage. The arcuate members are displaced radially outwardly against an elastic compressive force of the retention ring such that circumferential gaps are formed at joints between the neighboring arcuate members. The arcuate members are held in a condition movable in the circumferential direction by a distance equal to the size of the circumferential gaps.

摘要： The white chromaticity, in which the illumination environment is considered, is measured for each individual color monitor (100). A reference body (Q), comprising a perfect diffuser, is applied on the screen of the color monitor (100). By a test pattern display means (210), a test pattern (T) is displayed on the screen of the color monitor (100) based on tone values of the three primary colors R, G, and B that are stored in a tone value storage means (220). While fixing the tone value of the primary color R at 255, the tone values of the primary colors G and B are varied cyclically from 0 to 255 in a prescribed period by a tone value varying means (240). An operator inputs the result of comparing the color of the test pattern (T) and the color of the reference body (Q). When a comparison result indicating the matching of the two is input, a comparison result entering means (230) outputs an agreement signal. A measurement result output means (250) outputs, as the measurement results indicating the white chromaticity based on the reference body (Q), the tone values of the three primary colors R, G, and B that are stored in the tone value storage means (220) at the point at which the agreement signal is provided.

摘要： A pictorial image comprising pixels represented by a combination of density values in respect to first color components (R, G, B) is transformed to a pictorial image comprising pixels represented by combination of density values in respect to second color components (C, M, Y). In accordance with the first color modification method, an operation expressed as Q=.alpha.P+.beta. is implemented to an original density value P using two correction coefficients .alpha. and .beta. determined in advance to determine a density value Q after transformation. In addition, in accordance with the second color modification method, density values after transformation are determined by the calculation of the k-th degree masking equation using the k-th degree masking coefficients. At this time, a color cube is defined with respect to the first color components. The color cube thus defined is divided into an n number of blocks. The k-th degree masking coefficients are defined every respective blocks. Then, calculation of the k-th degree masking equation is performed using the k-th degree masking coefficients defined with respect to blocks involving points indicative of original density values within the color cube.

摘要： Surface indentation and oil film shortage on rollers is prevented and longer service life of a roller bearing is achieved, by preventing wear debris from being caught and accumulated in pockets of a holder of the roller bearing. Positions and dimensional relations of the diameters of inner and outer ring raceways, the inner and outer diameters of the holder, and inner and outer protrusions which are provided to pillar parts of the holder to prevent the rollers from coming off are defined such that the inner and outer protrusions of the pillar parts always do not come into contact with the outer circumferential surfaces of the rollers in the state where the rollers and the holder are incorporated between inner and outer members. As a result, lubricant oil is smoothly circulated in gaps formed between the outer circumferential surfaces of the rollers and the pillar parts of the holder.

摘要： An image formation apparatus is disclosed. The image formation apparatus includes a transfer effectiveness detector that further includes a computing unit for converting a sensor output voltage into a toner adhesion amount, and a transfer effectiveness detecting unit for obtaining transfer effectiveness by comparing a toner adhesion amount Td on a photo conductor with a toner adhesion amount Tb on a middle transfer object. Here, the toner adhesion amount Td is obtained by the computing unit converting an output of a photo conductor image detection unit, and the toner adhesion amount Tb is obtained by the computing unit converting an output of a middle transfer object image detection unit. When the transfer effectiveness detection unit determines that an abnormality is present in the transfer, whether the abnormality is due to decreased development capacity or due to decreased transfer effectiveness can be determined. If it is determined that the transfer effectiveness is less than a threshold value, a printing operation of the image formation apparatus is stopped given that the transfer effectiveness compensation is not possible.
