摘要： A multi-color electrophotographic apparatus is provided which includes a casing having an access cover (36A), an image transfer belt unit (37) for transferring a multi-colored image formed thereon a recording sheet, and an image-forming assembly (55) having a plurality of image-forming units. Each image-forming unit includes a photoconductor (46) and a developer (63) storing therein toner of a single different color for forming a different color toner image on each photoconductor (46). The image-forming assembly (55) is arranged to be movable between operative and inoperative positions. The operative position is such that each image-forming unit lies at an image-forming station with the photoconductor (46) thereof in engagement with an image transfer belt (38) of the image transfer belt (37) unit to transfer the toner image formed thereon in registration with one another to the image transfer belt for forming the multi-colored image. The inoperative position is such that all the photoconductors of the image-forming assembly are out of engagement with the image transfer belt for allowing an apparatus operator to unload the image transfer belt unit from the casing through the access cover (36A) without damaging each photoconductor due to rubbing with the image transfer belt.

摘要： A plurality of image forming units (1BK, 1C, 1M, 1Y) composed of a developing means having different electrostatic carriers and toners different in color are used. Each of the image forming units (1Bk), 1C, 1M, 1Y) can be moved to the same image forming position. The image forming unit is light exposed in image by the light exposing means (3) in the image forming position so as to effect an image forming operation, so that the toner images are transferred on the transfer material by the opposite transfer carrying means (31). In the color electrophotographic apparatus, the image forming units (1Bk, 1C, 1M, 1Y) of the image forming position are sequentially replaced and also, the transfer material is reciprocated by the transfer carrying means (31) so that the toner images of each color are put together, superposed in position and transferred on the same transfer material.

摘要： An electrophotographic apparatus including a photoreceptor drum (18) supported for rotation in one direction sequentially past a plurality of processing stations, a corona charger (20) for electrostatically charging the photoreceptor drum (18), a developer hopper (22) accommodating therein a mass of developing material (25) used to form a visible toner image and a transfer charger (28) for transferring the toner image onto a recording paper. The developer hopper (22) has its bottom portion formed with an opening open so as to accommodate a portion of the photoreceptor drum (18) so that the developing material (25) can be electrostatically deposited on the photoreceptor drum (18) including both non-image and image areas to form a toner layer. The apparatus also includes an electrode member (26) operable to electrostatically remove a portion of the toner layer covering the non-image area, thereby leaving the remaining portion of the toner layer in the image area to form the visible toner image. An electrophotographic method practised by the apparatus is also disclosed.

摘要： A multicolor electrophotography apparatus for forming a color image on a rotatable cylindrical image-holding means (11) is arranged to hold on its circumferential surface an electrostatic latent image optically formed by an exposing device. The apparatus includes a plurality of developing devices (31 to 34) movably provided along the circumference of the image-holding means (11) for developing a plurality of different-color toner images overlapping each other. Each of the developing devices (31 to 34) is selectively driven by development-selecting means including linearly moving means (35 to 37) for linearly moving the developing devices (31 to 34) to take a developing position and a non-developing position. The apparatus further includes rack means (41) which is provided with guide means (121a, 121b,...123a,123b) for moving each of the plurality of developing devices (31 to 34) between the developing and non-developing state. The rack means (41) is arranged such that at least the development devices (31 to 34) which are movable by said linearly moving means is removable from said rack means and insertable thereinto in directions which are substantially coincident with the approaching and separating directions.
