摘要： A digital half-tone image is reproduced by exposing a photoconductor by modulating the intensity of laser beam. In order to correct the effect of the size of laser beam on the gradation characteristic, the surface potential of the photoconductor is detected under various conditions. The sensitizing potential and the sensitivity of the photoconductor are corrected according to the measured values for stabilizing the gradation potential.

摘要： In an image forming apparatus with use of electrophotographic process, a plurality of toner images are formed on a photoconductor by changing stepwise a predetermined operating parameter such as light intensity of laser beam or the grid potential of sensitizing charger, and the densities of the toner images are measured. Thus, the value of the operating parameter is determined which corresponds with the smallest non-zero toner density among the measured densities. When an image is formed on the photoconductor, for example the gamma table is corrected according to the determined minimum light intensity.

摘要： In forming a digital image on the photoconductor wherein the intensity of the laser beam is modulated according to multi-level image data, a standard toner image is formed at an intermediate intensity at which the reproduced image density is not affected by the beam size, and the toner density is detected. On the other hand, the size of the beam for exposing the photoconductor is measured. Then, the gradation characteristic is controlled according to the toner density and the beam size. Thus, the effect of the beam size on the gradation characteristic is corrected.

摘要： In an electrophotographic image forming apparatus, a charger sensitizes the photoconductor at a desired initial potential and the photoconductor is exposed to form an electrostatic latent image, which is developed by a developer to form a toner image. A gradation correction table on the relation of the input image signal to the exposure amount is provided in a memory, and it is amended by adding a common amendment value to the image density signal in the gradation correction table. The common amendment value is determined according to the density of a standard toner image. If a plurality of gradation correction tables are stored in a memory, one of them is selected according to the output voltage of the charger or the bias potential of the developer. The selected gradation correction table is amended according to the surface potential of the photoconductor, the temperature of the photoconductor or the humidity of the photoconductor. Alternately, the detection value of the surface potential, the temperature or the humidity may be used to select the gradation correction table. The gradation table may be amended according to the state of the photoconductor. The amplification factor of the exposure amount for the photoconductor can be changed according to the state of the photoconductor, the temperature or the humidity of the photoconductor. The bias voltage of the developer or the output voltage of the charger may also be changed according to the state of the photoconductor.

摘要： The transporting speed of a developer transporting roller is switched over depending on the condition whether a developing unit is operated for developing process or the developing unit is not in action for developing operation, and a comparable standard value for making a decision whether toner replenishment is required or not is changed based on the toner density value detected by a magnetic sensor when the developing unit is operated or is not in action for developing operation. When the developing unit has finished a predetermined number of operations, and image forming operation is suspended, a developer stirring and transporting roller is driven for a duration of time corresponding to the number of developing operations conducted, and toner density detection and toner replenishment is carried out corresponding to the toner density detected.
