摘要： An image forming apparatus capable of preventing toner fusion between recording sheets, with a construction that does not require increase in cost and size of the apparatus and does not unduly lower productivity, to thereby offer high usability. For image formation on plural pieces of recording sheets, a CPU controls a recording sheet conveyance interval for a first set based on a detected amount of toner used for the image formation on each page, stores the toner use amounts for respective pages of the first set into a RAM, and controls the recording sheet conveyance interval for second and subsequent sets based on the toner use amount stored in the RAM for each page.

摘要： A method, system, and manufacture for adjusting electrostatic charges in a laser printer. A charge is applied to a photoconductor drum surface to create a dark voltage. An image area of the photoconductor drum is exposed with a printhead using a defined energy level to discharge the charge from the image area. An exposure voltage of the photoconductor drum is measured after the image area has been exposed. A first optimization is performed to determine an adjusted dark voltage and an adjusted energy level based on the measured exposure voltage and the dark voltage and the energy levels applied to the photoconductor drum. An applicator voltage is applied to an applicator that applies toner to the exposed image area of the photoconductor drum. Toner density applied to the photoconductor drum is measured and a second optimization is performed to adjust the applicator voltage to produce a target toner density.

摘要： An image forming apparatus has a photoconductive drum which carries an electrostatic latent image, a developer supply unit which supplies a developer to the photoconductive drum, an image carrier which carries a developer image, and a density sensor which measures a density of a test print on the image carrier. The image forming apparatus carries out a second image quality maintenance operation for lowering a contrast potential when the density of the test print is higher than a predetermined value. When the test print is still dense even if the contrast potential reaches a lower limit value, the image forming apparatus carries out a first image quality maintenance operation for discharging the developer, then supplying a fresh developer to the developer supply unit, and causing the developer to be stirred and thus charged.

摘要： An image forming apparatus includes an image carrier; a charger that electrically charges the image carrier; an image forming section that forms an electrostatic latent image on the image carrier and develops the electrostatic latent image; a transferring-fixing section that transfers the image from the image carrier and fix the image onto a recording medium; a cleaning member; and a cleaning member moving section. The cleaning member cleans an unnecessary substance adhering onto a surface of the image carrier by abutting against the surface of the image carrier, and is capable of moving between an abutment position and a separation position where the cleaning member is separated from the image carrier. The cleaning member moving section moves the cleaning member from the separation position to the abutment position in accordance with a surface resistance of the surface of the image carrier.
