    摘要： In a developing device, a receive-convey screw conveys a developer received from a developer carrier. The receive-convey screw includes a receive-convey blade including a lower, outer circumferential end located in a downstream end of the receive-convey blade in the developer conveyance direction of the receive-convey screw. A slant-convey screw is disposed obliquely relative to an axial direction of the receive-convey screw, and conveys the developer received from the receive-convey screw upward. The slant-convey screw includes a slant-convey blade including a lower, outer circumferential end located in an upstream end of the slant-convey blade in the developer conveyance direction of the slant-convey screw, the lower, outer circumferential end being located at a height level lower than the lower, outer circumferential end of the receive-convey blade.

    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.

    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： 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.

    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.
