    摘要: There is disclosed an image forming apparatus in which photosensitive member properties including potential properties of an exposed portion and unexposed portion of the surface of a photosensitive member irradiated with a light beam are estimated. An appropriate contrast potential and a developing bias voltage and charging grid bias voltage suitable for forming a high-density image are determined by a feedback control based on the photosensitive member properties. A laser power is changed to form an intermediate-density image whose density agrees with an intermediate-density target value. When the laser power is changed, the photosensitive member property changes. Therefore, the photosensitive member property is re-estimated, and the developing bias voltage and charging grid bias voltage are set again while maintaining the appropriate contrast potential.

    摘要: A toner sensor measures the amount of toner attached onto a photosensitive drum upon development by a developing unit. A controller compares the measured toner attaching amount with a predetermined reference value, and executes processing for changing at least one of image forming conditions, for example, the charging amount by a charger, the developing bias voltage of the developing unit, the exposure amount of an optical system, and the toner density of the developing unit, on the basis of the comparison result.
