摘要： Electrophotographic apparatus according to this invention are controlled in different ways such that quality of produced images is not affected by deterioration of the developing agent or the condition of the photoreceptor. A timer may be provided to detect the duration of a rest period to adjust the speed of development accordingly as well as by the number of copies produced. Similar control may be effected by measuring the surface voltage of the photoreceptor by a voltage detector and by adjusting the output level of the principal charger used for uniformly charging the photoreceptor prior to a development process.

摘要： An image formation apparatus having a cleaning process for removing defective toner from the developing unit during a non-image formation rotation of the photoreceptor drum. The image formation apparatus includes a reverse polarity charger for charging the photoreceptor drum to an opposite polarity from the polarity that is used for forming an electrostatic latent image. The reverse polarity charger allows defective toner to be removed from the surface of the photoreceptor during a warming-up process of the apparatus or after a predetermined number of image forming processes have been performed.

摘要： Before a photoreceptor for an electrophotographic image forming apparatus is uniformly charged at the beginning of a process for forming a latent electrostatic image thereon, the photoreceptor is exposed to charge-removing light for stabilizing the surface potential such that a high-quality image can be obtained. The level of exposure is modified in view of the fatigue and recovery characteristics of the photoreceptor. During a continuous operation of the photoreceptor, the level is logarithmically reduced. When the photoreceptor is started again after a rest period, the initial level of exposure is adjusted by logarithmically increasing it according to the length of the rest period as well as in view of the level of exposure prior to the rest period.

摘要： A photoreceptor having a marking area whose optical reflection property differs from that of a non-marking area is formed in a portion of a surface of an electrically conductive substrate. The average line of a vertical section of the non-marking area cut across the border line with the marking area is M.sub.0 and the average line of a vertical section of the marking area cut across the border line is N.sub.0 and that straight lines touching the average lines M.sub.0 and N.sub.0 at the intersection of M.sub.0 and N.sub.0 are tangent lines M.sub.1 and N.sub.1, respectively, the acute angle .theta. between M.sub.1 and N.sub.1 is within the range of 0.degree..ltoreq..theta..ltoreq.30.degree.. Setting the angle .theta. within this range enables a photoconductive layer of a uniform characteristic to be laminated on the electrically conductive substrate even when the marking area is formed on the surface of the substrate. With this arrangement, since information for optimizing the image quality of copies is obtained from the same location of a photoreceptor drum with reference to the marking area, a photoreceptor for electrophotography always produces copies of stable image quality.
摘要翻译：在导电性基板的表面的一部分形成有具有与非标记区域的光学反射特性不同的标记区域的感光体。跨越与标记区域的边界线切割的非标记区域的垂直部分的平均线为M0，并且跨越边界线切割的标记区域的垂直截面的平均线为N0，并且直线接触平均值 M0和N0交点处的线M0和N0分别是切线M1和N1，M1和N1之间的锐角θ在0°<30°的范围内。将角度θ设定在该范围内，即使在基板的表面上形成标记区域，也能够将均匀特性的光电导层层叠在导电性基板上。利用这种布置，由于从相对于标记区域的感光鼓的相同位置获得用于优化拷贝的图像质量的信息，所以用于电子照相的感光体总是产生稳定图像质量的副本。

摘要： A copying machine with a multiple transport function having a separation charger for separating from the photoreceptor surface copy paper with an image transferred thereon and a circulating transport passage formed from the paper discharge block to the paper feed block so that it is possible to select the single-sided copy mode for allowing the copy paper to be discharged outside the copying machine after the copying process, the duplex copy mode for allowing the copy paper undergoing one copying process to be led through the circulating transport passage to the copying process block as reversed, or the composite copy mode for allowing the copy paper undergoing one copying process to be led through the circulating transport passage to the copying process block without being reversed. The copying machine with a multiple transport function includes a current controller which sets current applied to the separation charger for the second copying process at a larger value in the composite copy mode and at a smaller value in the duplex copy mode than that for the copying process in the single-sided copy mode.

摘要： A box-shaped container (10) has an opening (12) and the opening is sealed tightly and doubly by a sealing material (13). The sealing material is hot-glued to a peripheral portion of the opening of the cartridge body to such an extent that the sealing material can be peeled from the peripheral part. The end portion (13a) of the sealing material is bonded at an adequate length from the free end to the face 11a of a side of the peripheral portion, and the free end portion is turned down for 180 degree angle to the outer side of the opening. Furthermore, the sealing material is bonded to the face (11b) of a opposite side of the peripheral portion side at which the free end portion (13a) is adhered and turned down to cover the opening in double covering. The sealing material also covers the turned-down end portion. The other end portion (13b) of the sealing material is attached to a roller (16), and as the user turns a handle (18) of the roller, the sealing material can be peeled off easily.

摘要： The present invention provides a process control stabilizing system including a cleaning device for the corona wires which allows the process control to be carried out optimally based on exact information which is obtained by certain sensors while a discharge from the main charger unit is kept uniform. The system is constructed so that an electrode cleaner is activated before the detection of the surface potential and/or the detection of the optical density, and in addition, the cleaning operation will be operated until the detection result falls within a predetermined range. Alternatively, the system causes detection of the surface potential and/or detection of the optical both before and after a cleaning operation by the electrode cleaner. The cleaning operation will be repeated until the difference between the first and second detections falls within a predetermined range. In the above operations, if the repetitions of the operations in excess of the predetermined number of times cannot make the detection result fall within the predetermined range, the system preferably activates a warning device and/or prohibits a copying operation.
