  • Publication number: 20190235410
    Abstract: An image forming apparatus includes one or more developing units, a detector, a voltage application unit, one or more exposure units, an image conveying member, one or more primary transfer members, a sensor, and a setting unit. The one or more developing units each include a photosensitive member and a developing member. The detector detects the one or more developing units. The voltage application unit applies a development voltage to the developing member. The one or more exposure units each expose the photosensitive member. The one or more primary transfer members each transfer, onto the image conveying member, a developer image. The sensor detects a developer amount on the image conveying member. The setting unit acquires developing unit information on a detection result from the detector, and sets a first-developing-unit development voltage, first-developing-unit exposure energy, or both on a detection result from the sensor and the developing unit information.

  • Patent number: 10187547
    Abstract: An image reading system includes a reading device, a first calibration unit, and a detection unit. The reading device is configured to read a white reference member to acquire white image data and configured to read an original document to acquire document image data. The first calibration unit is configured to calibrate shading of the document image data to generate first image data by performing converting a density value in the document image data to a gradation value that is proportional to the density value and falls within a predetermined range having a minimum gradation value, a maximum gradation value, and a target value less than the maximum gradation value. The density value equal to the corresponding density value is converted to the target value in the conversion. The detection unit is configured to detect pixels in the image data corresponding to an edge of the original document.

  • Patent number: 9628667
    Abstract: In a scanning apparatus, a controller is configured to obtain black reference data, compensated data based on digital data (scan data) by scanning a reference member with the light source turned off, and the black reference data. The controller further compares the compensated data with a first particular value. The controller executes the compensated data obtaining process with setting the light amount adjustment value to be a smaller value when the compensated data is greater than the first particular value, while with setting the light amount adjustment value to be a greater value when the compensated data is less than the first particular value. Further, the controller sets the light amount adjustment value to be a scan-time light amount adjustment value when the light amount adjustment value is equal to the first particular value. Then, the controller executes a scanning process according to the scan-time light amount adjustment value.
