摘要： An image recording apparatus for recording an image directly on a recording medium by transferring a toner to the medium. The toner is caused to fly toward the medium by small energy to form a high resolution image. A developing roller transports the toner in a predetermined direction. A flat electrode is located in the vicinity of the developing roller. A control electrode is provided on the flat electrode at a position where the flat electrode is remotest from the developing roller, while being electrically insulated from the flat electrode. The control electrode is made up of a number of recording electrodes and has an opening through which the toner may fly toward the medium.

摘要： An image forming apparatus includes a cleaning member for collecting toner left on an image carrier after image transfer, and then redepositing it on the carrier, so that a developing unit can collect the redeposited toner to reuse it. Even when the frictional charging ability of the cleaning member falls due to aging or varying environment, the charge of the toner left on the image carrier is regulated to preselected polarity before the toner reaches the cleaning member, thereby enhancing a toner collecting efficiency and a toner redepositing efficiency. The charge of the toner redeposited on the image carrier and moved away from the cleaning member is regulated to preselected polarity while being increased, thereby reducing a load to act on the developing unit. The toner is redeposited on the image carrier efficiently without regard to the polarity of the toner collected by the cleaning member. The developing unit is allowed to collect all the toner redeposited on the image carrier, thereby freeing the background of an image from contamination. When the cleaning member collects the toner from the image carrier, the toner is prevented from being transferred from the cleaning member to the image carrier, thereby obviating defective cleaning. An image forming speed is increased by reducing the interval between consecutive image forming areas. A pressure is caused to act uniformly between the cleaning member and the image carrier in the axial direction of the roller, further enhancing the toner collecting efficiency and toner redepositing efficiency while obviating background contamination.

摘要： In an image forming apparatus, a toner collection mode is executed when a series of image formation modes ends and when the image formation mode is continuously repeated a preselected number of times. A toner image sensing mode for sensing a reflection density from a reference toner image is executed every time the image formation mode is repeated a preselected number of times. The apparatus is capable of surely and efficiently removing toner left on an image carrier after image transfer, and collecting the reference toner image with a developing unit. The reference toner image is prevented from contaminating an image transferring unit and a cleaning unit.

摘要： In an image forming apparatus, during the course of recording, a cleaning roller is rotated together with an image carrier. The roller frictionally charges toner left on the image carrier after image transfer to the same polarity. A cleaning member electrostatically collects the charged toner. At the same time, a voltage is applied to the cleaning member by a voltage applying device in order to cause it to attract the charged toner, thereby cleaning the image carrier. Hence, even when the toner remaining on image carrier is charged partly to the positive polarity and partly to the negative polarity, the toner can be entirely transferred to the cleaning member by a simple construction.

摘要： An image recording apparatus for electrostatically forming a latent image on an image carrier by driving optics in response to multi-level image data. Before the start of an actual image recording operation, a latent image in the form of a test pattern having a plurality of tones is formed on the image carrier by pulse width modulation. A table for correcting image data is generated on the basis of sensed surface potentials of the test pattern. A semiconductor laser included in the optics is driven such that the tone data and the latent image potential remains in a constant relation.

摘要： An image forming apparatus is capable of specifying the type of an occurring abnormality to a certain extent while avoiding the increasingly complicated control that is caused when a plurality of abnormalities is detected individually according to the presence of their respective causes. A normal group data set, which is a collection of normal value combinations relating to grouped information constituted by a plurality of information of differing types, is stored in RAM or ROM serving as information storage means of a control unit. At least two or more sets of grouped information, comprising first grouped information constituted by a plurality of different types of information, and second grouped information constituted by a plurality of information in a different combination to that of the first grouped information, are obtained from the RAM, the ROM, various sensors, and an operation display unit. A CPU serving as determining means determines a Mahalanobis distance for each set of grouped information on the basis of the normal group data set and the obtained results of each set of grouped information, and uses this Mahalanobis distance to determine the presence of an abnormality according to categories.
