摘要： An image forming apparatus of the present invention includes a casing, an image forming unit, and an air conditioning device. The image forming unit includes a case accommodating at least a photoconductive element therein and formed with an opening for image transfer via which the photoconductive element is partly exposed to the outside. The opening is the only opening that might allow substances harmful to image formation into the case when the image forming unit is mounted to the casing. The air conditioning device removes the harmful substances flowing into the image forming unit from the outside.

摘要： An image formation apparatus has a branching claw with a first guide surface along a side of a sheet to be fed into a reversing path and a second guide surface along a side of a sheet to be fed out of the reversing path. This branching claw is disposed so as to enable switching between a first switching position where the sheet is allowed to be fed into the reversing path through its conveyance along the first guide surface, and a second switching position where the sheet is allowed to be forwarded from the reversing path toward the downstream side of a sheet conveying path through its conveyance along the second guide surface.

摘要： An image forming apparatus, particularly a color image forming apparatus, of the present invention distinguishes a register mark and the background of a conveying member on the basis of the level of a signal representative of the background and the peak value or the bottom value of the signal. The apparatus can therefore accurately detect deviation between images of different colors and correct it.

摘要： The color image forming method of the kind sequentially forming toner images of different colors on an image carrier with developers of corresponding colors stored in a plurality of developing devices, sequentially transferring the toner images to a single paper or similar recording medium one above the other, and returning the toner left on the image carrier after the image transfer to the developing devices color by color, and an image forming apparatus practicable therewith. After the transfer of a toner image of any particular color to the paper wrapped around a transfer drum, a cleaning roller assigned to the above color each collects the toner remaining on the drum and again deposits it on the drum. The drum conveys the redeposited toner to one of the developing devices storing a developer of the same color as the toner.

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.
摘要翻译：在图像形成装置中，在记录过程中，清洁辊与图像载体一起旋转。图像转印后，滚轮会摩擦将图像载体上剩下的墨粉充电至相同的极性。清洁部件静电收集带电的调色剂。同时，通过电压施加装置将电压施加到清洁部件，以使其吸引带电的调色剂，从而清洁图像载体。因此，即使剩余在图像载体上的调色剂被部分地充电到正极性并且部分地被充电到负极性，也可以通过简单的结构将调色剂完全转印到清洁部件。

摘要： A sheet feeder incorporated in an image forming apparatus and allowing the distance between the preceding sheet and the succeeding sheet to be reduced to a minimum necessary one. A pair of control rollers whose transport speed is controllable are located upstream of an image forming section with respect to an intended direction of sheet transport. An image transfer and paper separation unit is located at the image forming section. The transport speed of the control rollers is made higher than an image forming speed for any desired period of time after the leading edge of a sheet has been gripped by said control rollers and before the leading edge reaches the image forming section. As a result the distance between the preceding and succeeding sheets is reduced to increase the number of images which can be formed for a unit time without the transport speed at the image forming section being increased.

摘要： An image forming apparatus is provided with sensors for detecting existence of sheets of paper at a plurality of positions in transport paths within the image forming apparatus. A circuit part counts a number of sheets of paper remaining within the image forming apparatus when a transport abnormality occurs based on outputs of the sensors. This number of sheets of paper remaining within the image forming apparatus when the transport abnormality occurs is displayed on a display.
