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. Besides the above, a shielding member is provided and is opened only during a measurement mode of the toner sensor in order to prevent the toner sensor from being contaminated by toner during a non-measurement mode.

摘要： A toner depositing amount measuring apparatus for measuring the amount of toner deposited on a photosensitive drum includes a light source for irradiating the surface of the photosensitive drum with light and a photoelectric converting section for receiving the reflected light and converting the received reflected light into an electric signal. A logarithmic calculation is applied to the output signal of the photoelectric converting section in a logarithm-compressing section. The temperature characteristics of the logarithm-compressing section are compensated for in a temperature compensating section. The amount of the toner deposition is calculated in a toner depositing amount calculating section based on a difference between the data during non-deposition of the toner and the data during deposition of the toner, the data being obtained from the logarithm-compressing section. Further, image forming conditions are changed in a control section in accordance with an output signal denoting the calculated deposition amount of the toner so as to control the density of the image formed.
