摘要： Disclosed is apparatus for scavenging charged particles (e.g. triboelectrically carrier particles) from an electrographic recording element. Such apparatus comprises a conductive grid positioned in close proximity to the path of the recording element, and biasing means for electrically biasing the grid so as to attract the charged particles from the recording element yet prevent them from depositing on, and thereby contaminating, the grid.

摘要： Contrast and/or density adjustment of developed electrographic images is effected in a development system comprising a hard magnetic carrier and a magnetic brush having a rotary core and shell. The adjustment is effected by cooperatively varying the core and shell rotation rates, within predetermined ranges, in a manner which maintains the operative developer linear velocity generally equal to, and co-current with, the velocity of an electrographic image member's movement through the development zone.

摘要： Improved electrographic development apparatus and procedure for use with partially-conductive developer employs transport of the developer through a first development zone in a direction generally countercurrent to a moving image member and through a second development zone in a direction generally cocurrent to the moving image member. The extent of image development within each such zone is controlled by the rate of developer transport and/or the magnitude of developer bias, so that overall development of the different portions of large solid image areas (particularly leading and trailing portions of such areas) is equalized.

摘要： A module, included in an electrophotographic printer, for making toner images by a method in which transfer current for electrostatic transfer of toner images to receiver members is adjusted to compensate for ambient variations of toner charge-to-mass ratio (q/m). A predetermined functional relationship between transfer current and a control voltage parameter is utilized. Magnitudes of the control voltage parameter are derived from voltage measurements relating to creation of toner control patches on a photoconductive image-recording member included in a modular electrophotographic printer. Control voltage magnitude is linearly dependent on q/m. The functional relationship, which is characterized by three experimentally determined parameters, is co-optimized for providing efficient transfer of toner images and for minimizing back-transfer of toner away from a receiver member in a transfer station included in the module.

摘要： A series of toner images are formed on an endless belt having a splice. The toner images are transferred to a receiving sheet which is fed between the belt and a rotatable transfer member. The transfer member is cleaned by transferring toner back to the belt. Excess toner transfer from the splice of the belt to the transfer roller is obviated by either making the transfer member of a size that the toner will transfer back at an interframe area or applying a lacquer or other similar material to this splice to prevent the pickup of toner initially.
