| Number | Title | Issue Date |
| 5974291 | Image forming apparatus and image forming method using selective exposure and removal of liquid developer In an image forming apparatus, a supply roller 4 supplies a liquid developer to the photo-conductive substance of a photosensitive drum or belt prior to an electrostatic latent image forming process. The supply roller 4 is applied with a voltage dentical ... | 10/26/1999 |
| 5648841 | Apparatus for forming fixed images having encapsulated toner A method of forming fixed images including charging a photoconductor; exposing the photoconductor to light; developing an electrostatic latent image so that a toner is applied to the electrostatic latent image formed on the photoconductor to form a visibl... | 07/15/1997 |
| 5506668 | Image forming apparatus having toner removing device Image forming apparatus forms first and second toner images in the same portion of an image member. To prevent scavenging of toner in the first image into a second toning station, lightly held toner in the first image is removed from the image member prio... | 04/09/1996 |
| 5470686 | Image forming apparatus An image forming apparatus is constituted by an image-bearing member for bearing a latent image, and a developing apparatus for developing the latent image. The developing apparatus is constituted by a developer container for containing a developer, a dev... | 11/28/1995 |
| 5053821 | Electrophotographic image forming apparatus using photoconductive toner A photoconductive image forming apparatus in which charged photoconductive toner contacts a transparent insulating substrate and is exposed from within the substrate. Exposure reduces the resistivity of the toner so that its charge can be reversed by a bi... | 10/01/1991 |
| 5045879 | Image forming apparatus using photosensitive toner Disclosed is an image forming apparatus in which photosensitive toner remaining on an electrically-conductive drum after the formation of an image is collected and then used again for the subsequent process of forming an image. The apparatus comprises a t... | 09/03/1991 |
| 4990960 | Method and device for measuring densities of different toners constituting a mixture Disclosed are a method of and a device for measuring different kinds of photosensitive toners each being sensitive to light with a different range of wavelengths and contained in a photosensitive toner mixture which is used for forming a color image by a ... | 02/05/1991 |
| 4694310 | Method and apparatus of electrophotography A method and apparatus of electrophotography used for a printer or a copying machine, wherein a toner having no photoconductivity is applied on a surface of a photoconductive layer of a photoreceptor consisting of a transparent conductive layer and the ph... | 09/15/1987 |
