摘要： The increasing ratio of development density to increase in potential difference between a photoreceptor and a development roller differs between the region where the potential difference is small and the region where the potential difference is large. The increasing ratio of development density at the region where the potential difference is small is smaller than the increasing ratio of development density at the region where the potential difference is large. Development is conducted under the developing characteristics in which the upper limit of the development density at the region where the increasing ratio of development density is small is at least 0.3.

摘要： When a halftone image region that is below a predetermined density is to be reproduced, a processing unit controlling an exposure unit selects an exposure pattern that can represent a record dot diameter within a range based on a predetermined rule from exposure patterns prepared in advance. Accordingly, graininess is suppressed. When there are a plurality of exposure patterns that can be applied, the exposure pattern with the lowest number of dots present per 1 inch is employed. Accordingly, a halftone image is formed with the image reproducibility improved.
摘要翻译：当要再现低于预定浓度的半色调图像区域时，控制曝光单元的处理单元基于预先规定的曝光图案，基于预定规则从一个范围内选择可以表示记录点直径的曝光图案。因此，抑制了颗粒性。当存在可以应用的多个曝光图案时，采用每1英寸存在最少点数的曝光图案。因此，形成具有提高图像再现性的半色调图像。

摘要： An exposure energy control unit of an image forming apparatus controls exposure energy density Edot (&mgr;J/cm2) to be applied to an isolated one-dot pattern of image information to satisfy a relation −0.11P+6.4≦Edot/Eline≦−0.2P+10.7 where Eline (&mgr;J/cm2) represents exposure energy density applied to a line pattern of the image information having lines on every second lines and P (&mgr;m) represents dot pitch. Accordingly, image reproducibility of both of a periodic line pattern and an isolated dot pattern can be enhanced without decreasing the film thickness of a photoreceptor even if the resolution is high.

摘要： An exposure apparatus for image formation uses power control means provided to a laser driver for controlling exposure energy and accordingly forming an image. Specifically, exposure energy is varied depending on an isolated-dot pattern and an isolated-line pattern by changing the pulse height (drive power) of a drive pulse for each dot. Both of the isolated-line and isolated-dot patterns of a high resolution can thus be reproduced with a high image quality without increase of cost due to requirements for accuracy in processing and positioning of a lens and without decrease of life of a photoreceptor due to a decreased thickness of its photosensitive layer.

摘要： A developing device has a development roller for carrying toner on a surface thereof, a toner supply roller for supplying the toner to the development roller, a flat spring which comes into contact with the development roller, charges the toner to be supplied to the development roller and applies the toner to the development roller while regulating the thickness of a layer of the toner. The flat spring has a plurality of flat-plate parts including a contact flat-plate part which comes into contact with the development roller, and a curved part which connects the flat-plate parts to each other. In this structure, by arbitrarily selecting dimensional parameters of the flat spring, it is possible to easily obtain various flat springs having different properties. Therefore, for example, the stress to the toner and the stress to the members can be easily reduced simultaneously with a design of the flat spring. Moreover, it is possible to improve the uniformity of the toner layer thickness in the axis direction of the development roller and the uniformity of charging of the toner.

摘要： A hologram scanner includes a reproducing light source for generating a collimated reproducing light beam, a hologram disk being adapted to rotate, and a hologram disposed on the hologram disk for deflecting the reproducing light beam by diffraction so as to scan an image surface by the deflected reproducing light beam during a rotation of the hologram disk. The hologram has interference fringes recorded by a mutual interference of an object light of divergent spherical wave and a reference light of divergent spherical wave. The object light is generated by an object light source positioned at a first position apart from a hologram recording plane of the hologram disk, on which the hologram is to be recorded, by a first distance. The reference light is generated by a reference light source positioned at a second position apart from the hologram recording plane by a second distance. The first and second distances are different from each other so that the deflected reproducing light beam is focused on the image surface.
