摘要： A charger charges a recording medium before irradiation of light to form an electrostatic latent image by irradiating light as an optical image onto a surface of the recording medium. The charger includes a discharging electrode having a plurality of projections for generating corona discharge to charge the recording medium surface, a conductive shield case having an opening face opposite to the recording medium and opposed to the discharging electrode, a holding member for holding the discharging electrode in the shield case in a state in which the discharging electrode is electrically insulated from the shield case, a conductive grid electrode electrically insulated and held between the discharging electrode and the recording medium, and a power supplying device for supplying a high voltage for discharge to the discharging electrode and setting a ratio of electric currents flowing through the grid electrode and the shield case such that these electric currents are approximately equal to each other. One form of the charger controllably moves the discharger electrode toward the recording medium for setting the value of the electric currents flowing through the grid electrode and the shield case until they are both equal to a predetermined reference value.

摘要： An image forming apparatus adopting a non-magnetic one component developing system is arranged such that a charge brush and a developing roller are aligned along the circumference of a photoreceptor drum, that is rotatably driven, in order from an upstream side in a rotating direction of the photoreceptor drum. A transfer roller is placed opposing the photoreceptor drum with a sheet transportation path in-between. The charge brush, the developing roller and the transfer roller are rotatably driven while contacting the photoreceptor drum respectively. A photoconductive layer of the photoreceptor drum is made of an organic photoconductive material, and a coefficient of friction of the photoreceptor drum and the developing roller is selected to be not more than 0.5. As this eliminates the irregularity in rotary movement of the photoreceptor, offers a quality image and reduces a driving force for the photoreceptor drum, an apparatus of a light weight and high cost can be achieved.

摘要： An image forming apparatus includes: an image support medium; a charging member for charging the surface of the image support medium in contact with the surface of it; an exposure device for irradiating with light the surface of the image support medium charged by the charging member to form a static latent image; a developing device for supplying developer to the static latent image formed on the image support medium to develop the latent image and for removing the leftover developer on the image support medium; a transfer device for transferring the developer image, which has been developed on the image support medium by the developing device, to a member to be transferred; and a scraping member for scraping foreign matter such as dust and paper particles on the image support medium. The image forming apparatus is constructed such that the charging member causes the developer to adhere to the scraped foreign matter, and then the foreign matter is collected by the developing device through the image support medium. The scraping member is held by a holder which has an opening for allowing the foreign matter to pass through into the charging member housing.

摘要： Before a photoreceptor for an electrophotographic image forming apparatus is uniformly charged at the beginning of a process for forming a latent electrostatic image thereon, the photoreceptor is exposed to charge-removing light for stabilizing the surface potential such that a high-quality image can be obtained. The level of exposure is modified in view of the fatigue and recovery characteristics of the photoreceptor. During a continuous operation of the photoreceptor, the level is logarithmically reduced. When the photoreceptor is started again after a rest period, the initial level of exposure is adjusted by logarithmically increasing it according to the length of the rest period as well as in view of the level of exposure prior to the rest period.

摘要： A developer cartridge for image forming apparatuses which performs development to form images with non-magnetic, one-component type developer. The cartridge includes a developing roller for supplying developer to a photoconductor drum, a developer feed roller in non-contact with the developing roller for supply developer to the developing roller, and a developer-layer thickness control member for controlling the thickness of the developer layer on the developing roller. The developer feed roller is shaped as a regular polygonal prism. Since no recesses are formed in the surface of the regular polygonal prism, driving torque does not increase when developer is scrubbed from the prism, thus ensuring consistent operation and improved image quality. Non-magnetic, one-component type developer is compressed onto the developing roller by supplying the developer via the developer feed roller into a bottleneck between the developing roller and a developer applying member. The amount of developer which passes through the bottleneck onto the developing roller is controlled by a temporary reservoir, the pressurization thereof ensuring application of the developer to the developing roller. A control roller may be used against the developing roller to lower friction of developer, thereby preventing deposition of developer on the control roller while establishing a consistent amount of developer on the developing roller.

摘要： An electrophotography developing apparatus has been developed which can protect a developer holder and a layer thickness control member from damage. The device also prevents internal scattering of the developer while preventing a surplus supply of the developer to both ends on the peripheral surface of the developer holder. The unique advantages of the invention are derived through the utilization of sealing members having different elastic properties, which assume both bulk removal of excess developer while providing the needed uniform developer thickness. Another embodiment of the invention has the width of the layer thickness control member in a longitudinal direction set wider than the width of the developer holder in a longitudinal direction, and both side edges of the layer thickness control member are positioned outside both side edges of the developer holder. Proper sealing is assured by having the inner side edges of the sealing member positioned inside the side edges of the developer holder and outside the side edges of the image area of the image holder.

摘要： For input image data (`A`) before conversion, each pixel is converted into N (=3) parts. In this case, the three sub-pixels of data corresponding to a recording pixel (black pixel) are converted into recording sub-pixels on both sides of the three (`B`). This eliminates the density variation within a single pixel. Therefore, it is possible to reduce the dot spacing at slanted area, for example, and hence eliminate jaggies, providing a reproduced image easily recognized.

摘要翻译： 对于转换前的输入图像数据（'A'），将每个像素转换为N（= 3）部分。 在这种情况下，对应于记录像素（黑色像素）的三个数据子像素被转换成三（'B'）两侧的记录子像素。 这消除了单个像素内的浓度变化。 因此，例如可以减少倾斜区域处的点间距，从而消除锯齿状，提供容易识别的再现图像。
