摘要： 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.

摘要： 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.

摘要： An exposure apparatus is set to each color so that latent-image lines formed on photosensitive drums 1a to 1d have predetermined inclinations from rotation axes of the photosensitive drums 1a to 1d to form electrostatic latent images on the photosensitive drums 1a to 1d while performing curve correction on the photosensitive drums 1a to 1d. Peripheral speeds of the photosensitive drums 1a to 1d are controlled so that inclinations of toner images of a plurality of colors on an intermediate transfer belt become equal to each other. Thereby, each pixel is not shifted when light-scanning images are superimposed each other by the exposure apparatus 3 and it is possible to obtain a high-quality image free from image deterioration due to scanning irregularity caused by inclination shifts of scanning lines 3K, 3C, 3M, and 3Y.
