A voltage is applied to a conductive layer provided on an inner side of the transfer drum, and a grounded conductive electrode member is pressed against a dielectric layer provided on an outer side of the transfer drum through the transfer paper. A toner image formed on a photosensitive drum is transferred onto the transfer paper when the transfer paper is wound around the transfer drum and brought into contact with the photosensitive drum. The image forming apparatus further includes a member which charges the transfer paper in a polarity reversed to a polarity of the transfer drum, so that the transfer drum can attract the transfer sheet electrostatically in a satisfactory manner. The image forming apparatus further includes a charge control mechanism for controlling the amount of charges on the photosensitive drum. In addition the photosensitive drum has a voltage applying mechanism for applying a voltage to the internal surface of the drum.

摘要： In a laser printer having a serving semiconductor laser 14 as the printer engine part 3, the irradiation of a laser beam R, forming one pixel, is divided into a plurality of lighting times, and non-lighting times in response to clock horizontal synchronous signals CLKH1 and CLKH2, generated by a printer controller 2, so that the form of a light energy distribution, on a photosensitive body, for forming one pixel is made substantially trapezoidal. With this construction, the form of each dot of pixels composing an image is made substantially trapezoidal. This can lead to improving the image quality of any curve d portion and the sloped-line portion of the image, by reducing jaggedness.

摘要： A toner image fixing device realizes a stabilized fixing process by smoothly controlling a surface temperature of its heating roller, preventing peeling-off of a layer of the roller core. The toner image fixing device comprises a heating roller consisting of a core covered with a layer of, e.g., a silicon rubber, a heat lamp mounted in the heating roller and a pressure roller for pressing a sheet of paper against the heating roller. The toner image fixing device is provided with a temperature sensor for sensing a surface temperature of the heat roller and for operating the heater lamp at a preset ON-OFF ratio (e.g., 1:3) to elevate the heating roller surface temperature from a first preset value to a second preset value and thereafter to maintain it at the second preset temperature.

摘要： A copier capable of binding copy papers at their center or their edge as desired. A bookbinding device is operatively connected to a paper outlet of the copier. To bind the papers at their center, a folding mechanism of the bookbinding device is activated first in order to form a crease along the center of each copy paper. Then, a binding mechanism of the bookbinding device is activated to sequentially stack the papers in an upwardly convex form and such that the creases face upward in alignment and, then, stitch the papers together along the aligned creases by means of a staple or the like. The bound papers are discharged to a stacking mechanism of the bookbinding device in a developed position so as to be stacked there while being folded double in the creases. When it is desired to duplicate documents on papers which are equal to or double the size of the documents and bind the copies at the center, a positional relationship between the documents and the papers is set up by a unique method.
