An image forming apparatus includes: image forming units provided detachably and each having a developing roller for supplying a toner to an electrostatic latent image formed on a charged photoconductor drum to form the electrostatic latent image into a visible image; an endless intermediate transfer belt which is provided in such a manner as to be capable of abutting against the photoconductor drum and is adapted to rotate in loop form by being supported in a tension-adjusted state by a plurality of rollers, and onto which a toner image developed on the photoconductor drum is transferred; and a high-voltage unit which is electrically and mechanically connected to the image forming units through terminals to supply predetermined electric power to the photoconductor drums, chargers, and the developing rollers of the image forming units. The image forming units are arranged to be moved in a width wise direction of the intermediate transfer belt so as to be connected to the high-voltage unit.

Image forming apparatus

An image forming apparatus includes a photoconductor drum in which a first gear portion is formed on the axis of rotation and on which an electrostatic latent image corresponding to a toner image is formed by a rotation in a circumferential direction; a developing roller which is set correspondingly to the photoconductor drum, and makes visible the electrostatic latent image formed on the photoconductor drum thereby to form a toner image; and a photoconductor drive shaft having a second gear portion engaging with the first gear portion and formed on an axis of rotation, which gears with the photoconductor drum on the same axis and rotation-drives this photoconductor drum. Further, in at least either of the first gear portion and the second gear portion, an axial length of a part of gear teeth constituting the gear portion is different from axial lengths of other teeth.

A color image formation apparatus includes a plurality of stages of photosensitive drums provided for respective developing agents, the photosensitive drums arranged in a predetermined direction; and developer units which are provided for respective photosensitive drums and which develop electrostatic latent images formed on the photosensitive drums, wherein an overlap exists in the predetermined direction between a portion of each photosensitive drum and a portion of the developer unit provided so as to correspond to an adjacent photosensitive drum.

Disclosed here is a color-image forming apparatus that minimizes damage caused by friction between a photosensitive drum and an inter-stage transfer belt. The apparatus includes a plurality of image-forming units, each of which has the photosensitive drum carrying an electrostatic latent image thereon, a developing unit forming a toner image by applying toner to the latent image. Having different color toners therein, the image-forming units are organized into a tandem layout. The inter-stage transfer belt is looped over plural rollers to form an endless path. While traveling the path along the direction in which the image-forming units are arranged, the belt forms a full-color toner image thereon by transferring plural toner-images on the drums one upon another. The belt is controlled to come into contact with the drums only while accepting the toner image from the drums.

Color image forming apparatus that minimizes contact between transfer belt and photosensitive drum

An image developing apparatus has a photosensitive body, an image-developing roller, a toner feeding roller, a housing cassette, whereon the image-developing roller and the feeding roller are mounted, for storing the toner, a plate-like blade mounted on the housing cassette, a sheet member for preventing the toner from leaking, and toner sealing devices made of a resilient material for preventing the toner from leaking. The sheet member is displaced between a development area of the developing roller and a position of the pressed contact between the developing roller and the feeding roller. The sheet member maintains a uniformly contact along a longitudinal direction of the developing roller. The toner sealing devices are either mounted integrally to, or formed integrally with the blade as one unit, and provided at both ends of the blade. A space is provided between the toner sealing devices and the housing cassette. The structure of this invention realizes prevention of the toner from leaking in the image developing apparatus, since it effectively fills a space between the blade and the developing roller. Furthermore, the structure also improves productivity and reduces working processes, since it makes adhesion of the toner sealing devices unnecessary in manufacturing the image-developing apparatus.

A color image-forming apparatus includes an endless belt-like photosensitive member stretched between and wound around a drive roller and a driven roller, and a plurality of developing rollers making contact with an outer surface of the photosensitive member. At least one flexure correction shaft is held in contact with an inner surface of the photosensitive member on the side remote from the developing rollers. With this construction, the condition of contact between each developing roller and the photosensitive member is made stable and uniform, and the developing conditions for all the colors become uniform so that a high-quality image can be obtained.
