摘要： A method of removing a film from a photoconductive element of a color copier or similar image forming apparatus. At a suitable time when an image forming mode operation for forming a toner image on the photoconductive element is not under way, an amount of cleaning agent great enough to scrape a film off the photoconductive element is transported to a region between the photoconductive element and a cleaning sleeve. Subsequently, the amount of cleaning agent to be transported to such a region is reduced. This sequence of steps is repeated a plurality of times.

摘要： A method of removing a film which undesirably forms on a photoconductive element or similar image carrier of an image forming apparatus such as an electrophotographic copier, printer or facsimile machine. The method is implemented by a cleaning device having a cleaning sleeve which removed toner particles remaining on the image carrier after image transfer. In a film removing mode which is executed when an image forming mode for forming a toner image on the image carrier is not under way, the cleaning sleeve is rotated at a lower speed than in an ordinary cleaning mode so as to feed a greater amount of cleaning agent to a cleaning region. The rotation speed of image carrier and that of the cleaning sleeve are controlled in such a manner as to feed a predetermined adequate amount of cleaning agent for the removal of a film to the cleaning region at all times.

摘要： An electrophotographic copying process and apparatus fast in operation and capable of making reproduced images having substantially the same image density is provided. In accordance with the present invention, pre-exposure is carried out only when a photosensitive member is to be used for image formation after elapsing a predetermined time period during which the photosensitive member has been kept unused. The present invention is fast in operation and minimal in power consumption because the pre-exposure is skipped when unnecessary. However, since pre-exposure is effected when necessary, the image density may be maintained at constant.

摘要： An image density control method for an image forming apparatus of the type forming a latent image of a document image on a photoconductive element and developing the latent image by a toner to produce a toner image by an electrophotographic procedure. A background pattern whose density is substantially the same as the background density of a document, i.e., a light pattern is illuminated to electrostatically form a latent image thereof on the photoconductive element. The latent image is developed by the toner, and the density of the resultant toner image is optically sensed by an image density sensor. A change in background density due to contamination or an increase in background potential, for example, is detected. Based on the detected change in background density, a quantity of light for imagewise exposure or similar factor dictating the developing ability is corrected, i.e., it is controlled to the light side if the density has been shifted to the dark side. The detection of the background density and the control for correction are effected only when the charge retaining ability of the photoconductive element is stable.

摘要： An original to be copied is placed in a given position. An exposure optics including a movable part is employed to focus an optical image of slitwise segment of the original on a photosensitive member. The photosensitive member moves in a given direction and at a given speed throughout the exposure. The location where the image of slitwise segment of the original is focused moves through the space of the arrangement at a given speed and in a direction opposite from the direction of movement of the photosensitive member throughout the exposure. Consequently, the location corresponding to the initiation of the exposure is situated downstream as viewed in the direction of movement of the surface of the photosensitive member while the location corresponding to the end of the exposure is situated upstream as viewed in the same direction. Upon termination of the exposure, the photosensitive member continues its movement which is the same as during the exposure while the movable part of the exposure optics returns to its start position.

摘要： A dual mode method for controlling the density of a toner image is disclosed for an electrophotographic process. In the first mode, an electrostatic latent image is formed on a photosensitive member from a reference pattern having a predetermined reflectance, the latent image is developed, the density of the developed image is detected, and this density information is used to replenish toner to the developer. A second mode can be actuated in which the photosensitive member is excited to form a region of approximately saturating residual potential which is then developed under a predetermined bias potential, the density of the thus developed image is detected and the density information is used to determine whether the developing step is functioning properly.
