摘要： An image forming apparatus is disclosed, in which a photo-sensitive member is exposed by exposure means accommodated therein, and development is done substantially simultaneously with the exposure.Three time elements, that is, charging time constant C, i.e., time until reaching of a predetermined charging potential on of the photo-sensitive member in a brushing contact region between the photo-sensitive member and a toner holder after the start of charging, exposure time constant R, i.e., time until the charging potential is attenuated by the exposure to a latent image potential, and development time or time T, during which the photo-sensitive member passes by the brushing contact region, are appropriately determined.It is found that more satisfactory image formation is possible by setting C, R and T such as to meet relationsC+R

摘要： An apparatus for printing directly on plain paper, utilizing an arrayed control grid having a plurality of toner slots disposed in a space between a toner carrier and a backing electrode on which a paper travels. The backing electrode formed in a flat plate facing paralleledly to the control grid assures a uniform electrostatic field in an interspace therebetween. A unit body associated with the toner carrier and the control grid makes the interspace open when the unit body is removed from the apparatus body which offers an easy access to the interspace and the members as well. A resiliently suspended backing electrode with a spacer, a restriction member etc., assures the interspace constant. Other unit bodies including the control grid associated with the backing electrode and others are also disclosed.

摘要： An apparatus and method for printing directly on plain paper, utilizing an arrayed control grid having a plurality of toner slots. An alternating electrostatic field in a space between a toner carrier and a backing electrode gives toner a vibrational motion to prevent a toner clog at the slot. The field is also formed to repel the clogged toner back to the toner carrier, or to fall it down on a paper on the backing electrode during no print is performed to clean the control grid. A constitution of conductive and dielectric materials for the members assures to form the field.
