摘要： A method for determining the approximate surface conductivity of a photoreceptor surface. The method involves forming a latent image of a series of lines of different widths on the surface, developing the image, and then printing the image. Based on which lines print, the surface conductivity can be computed once the developability of isolated lines is established through a calibration procedure.

摘要： An image forming apparatus includes a photosensitive member, a charging device, a developing device, a thickness detecting unit and a parameter setting unit. A photosensitive layer is formed on a surface of the photosensitive member. The charging device charges the photosensitive member. The developing device forms a toner image on the surface of the photosensitive member. The thickness detecting unit detects a thickness of the photosensitive layer on a basis of a value of a current supplied to the charging device. When the thickness detecting unit detects the thickness of the photosensitive layer, the parameter setting unit sets at least one of a charge parameter for the charging device and a development parameter to be different from that used in forming an image on a recording medium by transferring a toner image formed on the surface of the photosensitive member onto the recording medium.

摘要： An image forming apparatus includes: a toner image carrier which carries a toner image thereon; a recording medium selection information input section to which recording medium selection information is inputted to select a recording medium to which the toner image carried on the toner image carrier is transferred; a fog controller which sets a fog control parameter value to control a fogging level of the toner image carrier; and an image forming section which forms the toner image to be carried on the toner image carrier based on the fog control parameter set by the fog controller. The fog controller sets the fog control parameter value so that the fogging level of the toner image carrier when the recording medium selection information inputted corresponds to a coated sheet, is lower than that when the recording medium selection information inputted corresponds to a normal sheet.

摘要： An image forming apparatus which is capable of eliminating density irregularities of an image formed caused by potential irregularities of the photosensitive member when the drum is irradiated by a beam of constant luminous intensity. A laser driver irradiates a beam modulated based on an image signal onto a photosensitive member. A current controller variably controls a driving current for driving the laser driver. A PWM pulse width converter modulates a pulse width of the beam based on the image signal. A potential sensor measures the potential of the photosensitive member after the photosensitive member is irradiated by a beam having a predetermined luminous intensity. A selector causes the current controller to correct the driving current based on low frequency components of irregularities of the potential and changes a modulation coefficient used for modulating the pulse width based on high frequency components of the irregularities of the potential.
