摘要： A cleaning element is arranged on the backside of the toner layer metering blade, i.e., the side opposite to the surface in contact with the developer support, in order to prevent the cleaning element from damaging the blade surface and the abutment surface of the metering blade against the developer support. This cleaning element is frictionally moved across the backside of the toner layer metering blade to remove stuck toner from the toner layer metering blade or prevent occurrence of buildups.

摘要： In image forming apparatuses producing recycled toner from residual toner and recycling the recycled toner, the toner composition changes, and the toner properties worsen, because the external additive contained in the collected residual toner that is collected with a cleaning portion decreases during the image formation. The residual toner that has been collected with the cleaning portion is conveyed through a conveyance path to a collected residual toner storage, and external additive is supplemented from an external additive cartridge, and mixed with being stirred to produce recycled toner. In a fresh toner storage, fresh toner and recycled toner are stirred, and when the amount of toner in a developing portion drops below a predetermined amount, toner is conveyed from the fresh toner storage through a conveyance path to the developing portion. The toner that has been conveyed to the developing portion is supplied to a photosensitive drum.

摘要： A developing device, includes; a developing roller supporting and conveying mono component toner to a photoreceptor having a static latent image; a supplying roller pressed against the developing roller and rotated so as to supply the toner to the developing roller. In order to perform beneficial supply of the toner to the developing roller, bias voltages are applied so as to generate an electric field which will cause the toner between the developing roller and the supplying roller to be attracted to the developing roller. At a predetermined time before completion of development, the bias voltage applied to the supplying roller is switched so as to create an electric field which will cause the toner to be attracted to the supplying roller. Thus the toner residing between the developing roller and supplying roller after development is removed, whereby it is possible to prevent toner from sticking to that area on the developing roller, after development. Another configuration further includes a cleaning roller abutted on the supplying and regulating rollers. When development is completed, rotation of the developing roller is stopped. In time with this, the supplying roller, regulating roller and cleaning roller are kept on rotating for a predetermined period while the bias voltages are switched so that the direction of the electric fields acting on the toner, formed between the rollers after switching are opposite to those formed during development.

摘要： An object of the invention is to make an exact judgment on suitability of a replaceable component such as a toner supplying container with use of an existing mechanism of an image forming apparatus, without additionally providing a data storage component designed for a consumable product which is detachably attached to the apparatus, or a data reading component to be placed in the image forming apparatus main body. In an incorporated control section, a specific part of a replaceable component, which is placed on an original platform prior to being loaded into the apparatus, is optically scanned to read image information, and, based on the reading result, whether or not the replaceable component is suitable for the image forming apparatus is judged.

摘要： Toner image forming means for forming toner images having chromatic colors of Y, M and C, respectively, are disposed on one side of an intermediate transfer belt, while disposing toner image forming means for forming a black toner image on the other side of the intermediate transfer belt, alone and on a most downstream side of all the toner image forming means. Further, when a toner image on the intermediate transfer belt includes toner having a reverse polarity, a transfer or developing process is controlled to reduce electrostatic attraction force acting on an image carrier, thus providing a color image forming device having a main body reduced in size and capable of faster image formation of a monochromatic image which is more frequently used, and of efficiently forming a color image by suppressing a back-transfer phenomenon and improving color reproducibility.

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： In case of a developing density correction based on a test image (patch image) density, normally, the developing density is carried out in a short period of time by correction (γ correction) of a developing bias and a grid voltage (S11). When a correction amount of the γ correction exceeds an ordinary range, the γ correction (S11) and adjustment of toner concentration (magnetic permeability reference value) (S5) are carried out in combination. Furthermore, when the toner concentration is changed, the setting of a correction reference of the γ correction (γ correction TBL) and correction timing of the γ correction are accordingly changed (S6, S7). Therefore, in the developing density correction based on the test image density in the developing device using binary developer, it is possible to carry out the developing density correction, which is carried out in a short time, and whose correction width is wide, while maintaining the accuracy of a developing density adjustment.

摘要翻译： 在基于测试图像（贴片图像）密度的显影浓度校正的情况下，通常，通过显影偏压和电网电压的校正（伽马校正）在短时间内进行显影密度（S11） 。 当伽马校正的校正量超过普通范围时，组合进行伽马校正（S11）和调色剂浓度（磁导率基准值）（S 5）的调整。 此外，当调色剂浓度改变时，相应地改变伽马校正（伽马校正TBL）的校正基准的设置和伽马校正的校正定时（S6，S7）。 因此，在使用二次显影剂的显影装置中基于测试图像浓度的显影浓度校正中，可以执行在短时间内执行的显影浓度校正，并且其校正宽度大，同时保持 发展密度调整的准确性。
