摘要:
Image-forming apparatus includes an electron beam generator responsive to image-defining excitation signals to apply a pattern of electron beams to a plate. The plate thereupon emits radiation in pattern according with the electron beam pattern.
摘要:
A method and device used with an electronic photocopying apparatus and for removing any residual developing solution from a photosensitive member by the use of a corona discharger to thereby provide a perfect copy of an original image.
摘要:
A device for removing dielectric liquid from a holder member for a photosensitive medium or the like used in an electrophotographic copying machine includes a corona discharging electrode, a shield member substantially surrounding the corona discharging electrode in electrically isolated relationship therewith and having at least a discharge opening, corona discharge converging means provided adjacent to the discharge opening of the shield member, and a power source from which a voltage is applied to the corona discharge electrode.
摘要:
In an electrophotographic process, visual images obtained by developing electrostatic latent images with a liquid developer are transferred to a transferring paper having oil absorbing coefficient ranging from 1.0 X 10 4 to 5.0 X 10 2 cm./sec. and smoothness by Bekk tester ranging from 30 to 150 seconds.
摘要:
THE PHOTOSENSITIVE MEMBER CONSISTS BASICALLY OF A SUPPORTING BASE, A PHOTOCONDUCTIVE LAYER AND INSULATING LAYER DYED IN A DESIRED COLOR FOR PROVIDING A COLOR FILTER EFFECT. SUCH PHOTOSENSITIVE MEMBERS HAVING DIFFERENT COLOR FILTET EFFECTS ARE PROVIDED FOR POLYCHROMATIC REPRODUCTION ON A SINGLE TRANSFERABLE MATERIAL.
摘要:
A cleaning device for an electrophotographic copying apparatus comprising a photosensitive medium having liquid collection grooves formed at the opposite end portions thereof, and a cleaning blade of resilient material having an edge adapted to bear against the surface of the photosensitive medium. The cleaning blade has projections formed at the opposite ends thereof so that when the blade is brought to its cleaning position, the inner side walls of the projections thereof may keep liquid-tight contact with the inner side walls of the liquid collection grooves. Thus, relative sliding movement between the blade and the photosensitive medium removes any amount of developing liquid remaining of the surface of the photosensitive medium after an image transfer has been completed.
摘要:
Various structures are disclosed for producing a layer of liquid developer to cover the visible portion of an edge mounted section of an electrophotographic recording medium without wetting the mount beyond the edges bordering said visible portion. During application of the developer to said visible portion there is no relative movement of the developer device across the surface of the visible portion.
摘要:
An electrophotographic copying machine of the type using a drum type photosensitive medium provided with a cleaning system. The cleaning system includes a blade of resilient material oriented in a counter-direction relative to the direction of movement of the photosensitive medium and having one edge disposed in contact with the medium, a cleaning tank, and circuitry for applying cleaning liquid to the areas of the medium and the blade near the contact area therebetween before the process is started.
