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.

摘要： A cleaning device of the present invention is configured to remove toner left on an image carrier after the transfer of a toner image from the image carrier to a recording medium. A rotatable cleaning roller contacts the image carrier for removing the toner left on the image carrier. A rotatable brush roller is positioned upstream of the cleaning roller in the direction of rotation of the image carrier and rubs against the surface of the image carrier and that of the cleaning roller. The cleaning device is free from defective cleaning despite the use of spherical, dry toner grains capable of forming high-quality toner images.

摘要： A charging device is provided. The charging device comprises a charging member having two spacers made of tape, and the charging member is pressed to contact with the non-image forming region of an image supporter. The surface of the charging member between the spacers is opposite to the surface of the image supporter by a tiny gap. A charging voltage is then applied to the charging member to charge the image supporter. As the image supporter rotates, a large variation of the tiny gap can be avoided. The pressing force of the spacers against the image supporter is set at 4 N to 25 N (Newton), and in a moving direction of the surface of the supporter, a contact width of a contact portion where the spacer is pressed to contact with the image supporter is set below 0.5 mm.

摘要： A modular type image forming system includes a laser printer main unit and a plurality of optional units, such as a both side processing unit, a large quantity paper feeding unit and a mail box unit, each of which is operatively coupled to said main unit through a commonly usable optical fiber cable through a commonly usable connector. Each unit has its own CPU and serial communications between the CPUs of different units may be carried out through the optical cables. The CPU of the main unit may determine the identity of each of the optional units connected thereto through such communications. The main unit also includes an interface circuit through which the main unit is operatively coupled to each of the optional units. The interface circuit includes a port selector which establishes a connection pattern between the main and optional units in accordance with the identity information of each of the optional units connected. When paper is fed into a transportation path, paper ID is assigned to the paper and retained until the paper is discharged. If the paper is removed from the path without passing a predetermined location, the same image is printed again.
