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.

摘要： According to one embodiment, a document detecting apparatus includes a light-emitting element, a photoelectric conversion element, a light-emission controller and a detection processor. The light-emitting element projects light onto a detection position of a document. The photoelectric conversion element outputs an electric signal obtained by converting the light from the detection position of the document. The light-emission controller changes the light quantity of the light emitted by the light-emitting element. The detection processor detects the presence or absence of the document at the detection position of the document based on the presence or absence of a change of an output value corresponding to the change of the light quantity caused by the light-emission controller in an output value from the photoelectric conversion element.
