摘要： In an example of a method for reducing contamination, a purified imaging oil is formed by filtering an imaging oil through an imaging oil filter, and then filtering the imaging oil through a polar absorbent filter. A surface of an amorphous silicon photoconductor of a liquid electrophotographic printing apparatus is maintained by periodically applying the purified imaging oil to the amorphous silicon photoconductor.

摘要： A color image forming method, including the steps of: charging a front surface of a photoreceptor; conducting image wise exposure onto the charged front surface from a rear surface of the photoreceptor so that a latent image is formed on the front surface; developing the latent image with a color toner so that a color toner image is formed on the front surface; and repeating the steps of charging, conducting image wise exposure and developing so that a multicolor toner image is formed on the front surface; in which a secondary color of the multicolor toner image, which consists of two color toner images, is formed in a manner that the two color toner images are formed by conducting the image wise exposure at a same exposure amount; and the first one of the two color toner images is formed by conducting the image wise exposure at an exposure amount which creates a potential smaller than that of already formed primary color of the multicolor toner image, which consists of single color toner image.

摘要： An image-forming apparatus, for example, electrophotographic printer has a replaceable cartridge (3) which includes an image member (2), for example, a rotatable photoconductive drum. The drum cooperates with a transfer member (10), for example, a transfer drum which transfer member must be cleaned. The cartridge includes a chamber (35) for receiving toner cleaned from the transfer member. Preferably, the image-forming apparatus creates a series of color toner images which are transferred to the surface of the transfer member in registration to create a multicolor image. The multicolor image is transferred in turn to a receiving sheet. The residual toner on the transfer member can be cleaned either by a cleaning device (30) permanently located in the apparatus or a cleaning device (60; 70) in the cartridge. In either instance, the toner is collected in the cartridge and therefore does not require separate maintenance beyond replacement of the cartridge.

摘要： A developing apparatus in which a stationary multipole permanent magnet (4) is placed in a sleeve (3) and in which a development is performed by bringing a developer (7), which contains at least carrier and toner particles and is held on the periphery of a sleeve (3) by use of the magnetic force of the multipole permanent magnet (4), into contact with a photo-conductive body (1) owing to the rotation of the sleeve (3). For securing of image density and for preventing of the deposition of carrier onto the photo-conductive body (1), two magnetic pieces (18, 19), each of which is arranged lengthwise in the direction of the axis thereof and has same polarity, are placed in a region in the multipole permanent magnet (4), which faces the photo-conductive body (1), in such a manner as to adjoin in the circumferential direction of said permanent magnet (4). This results in generation of the distribution of a magnetic field, which have two peaks of the magnetic force. The position, at which a second one of the two peaks of the magnetic force is formed downstream in the direction of rotation of the sleeve (3), is set at the nearest point between the photo-conductive body (1) and the sleeve (3). Thereby, even when a development is performed by bringing the developer (7) into light contact with the photo-conductive body (1), the image density can be secured. Further, the carrier can be prevented from depositing on the photo-conductive body (1).

摘要： An image forming apparatus includes an image member (2) supplied to the apparatus in an image member cartridge (3) and a transfer member (10) which engages the image member through an access opening in the cartridge. The transfer member (10) is driven by a motor (40; 212), which may be inside the transfer drum, in the image forming apparatus and in turn drives the image member (2) in the cartridge, eliminating the need for a separate driving connection between the image forming apparatus and the image member cartridge. The cartridge is mounted in the image forming apparatus by a pair of control surfaces (115) which are fixed with respect to the shaft (111) of the transfer drum along with extensions of the shaft (105) of the image member are urged by a spring (120).

摘要： This apparatus comprises a photosensitive drum; exposing means for forming a plurality of electrostatic latent images on the photosensitive drum one after another in accordance with the color-separated printing information; means for developing the electrostatic latent images on the photosensitive drum one after another by toners having the hues corresponding to the color-separated printing information to turn them into toner images; and intermediate transfer medium which is pressed to the photosensitive drum so that the toner image on the photosensitive drum is transferred to it one after another and a multi-color toner image is formed on it; means to transport a recording medium to and from the intermediate transfer medium in order to transfer and fix the multi-color toner image formed on the intermediate transfer medium to the recording medium; and a thermally fixing means which is pressed to the intermediate transfer medium through the recording medium. A plurality of electrostatic latent images in yellow, magenta, cyan, and black in that order are formed on the photosensitive drum in accordance with the printing information separated for yellow, magenta, cyan, and black. The electrostatic latent images are developed by use of toners having hues corresponding to the color-separated printing information in order to form the yellow, magenta, cyan, and black images in that order. The respective color toner images are transferred to the intermediate transfer medium sequentially in the order of yellow, magenta, cyan, and black to form a multi-colored toner image on the intermediate transfer medium. This multi-color toner image is transferred and fixed to the recording medium.

摘要： Appareil servant à former des images, tel qu'une imprimante électrophotographique, comprenant une cartouche remplaçable (3) comportant un élément d'images (2), par exemple un tambour photoconducteur rotatif. Ledit tambour coopère avec un élément de transfert (10), tel qu'un tambour de transfert dont l'élément de transfert doit être nettoyé. La cartouche comprend une chambre (35) destinée à recevoir le toner éliminé de l'élément de transfert. De préférence, l'appareil servant à former des images crée une série d'images de toner en couleur qui sont transférées sur la surface de l'élément de transfert aligné, pour créer une image polychrome. Cette image polychrome est ensuite transférée à sont tour sur une feuille réceptrice. Le toner résiduel se trouvant sur l'élément de transfert peut être éliminé par un système de nettoyage (30) fixé à demeure dans l'appareil ou bien par un système de nettoyage (60; 70) situé dans la cartouche. Dans les deux cas, le toner vient s'accumuler dans la cartouche et ne nécessite donc pas de surveillance particulière en dehors du remplacement de la cartouche.
