摘要： In an electrophotographic recording apparatus of the type using a single-ingredient type developer, i.e., toner, a developing device has a developing roller for conveying the toner deposited thereon, and an intermediate roller for conveying the toner transferred theretofrom the developing roller and depositing it on a latent image electrostatically formed on an image carrier to thereby produce a corresponding toner image. During the development of an area of the image carrier other than a latent image area, a bias assigned to the developing roller is switched over to thereby form an electric field different in direction from an electric field assigned to the formation of the toner image between the two rollers. Further, before the rotation of the image carrier is stopped, the bias assigned to the developing roller is again switched in order to form the electric field for the formation of the toner image between the rollers. As a result, a toner layer is formed on the intermediate roller. Subsequently, the rotation of the image carrier is stopped. The device obviates defective images ascribable to the adhesion of the image carrier and intermediate roller while eliminating background contamination and wasteful toner consumption.
摘要翻译：在使用单成分型显影剂（即调色剂）的电子照相记录装置中，显影装置具有用于输送沉积在其上的调色剂的显影辊和用于输送从显影辊转移到其上的调色剂并将其沉积的中间辊在静电形成在图像载体上的潜像上，从而产生相应的调色剂图像。在除了潜像区域之外的图像载体的区域的显影期间，分配给显影辊的偏压被切换，从而形成与分配给形成调色剂图像的电场不同的方向的电场两个滚筒。此外，在停止图像载体的旋转之前，再次切换分配给显影辊的偏压，以形成用于在辊之间形成调色剂图像的电场。结果，在中间辊上形成调色剂层。随后，停止图像载体的旋转。该装置消除由于图像载体和中间辊的粘附而导致的不良图像，同时消除背景污染和浪费的调色剂消耗。

摘要： In an image forming apparatus, a developing device has a first developer carrier for depositing a developer thereon, a regulating member for regulating the amount of the developer deposited on the first developer carrier, and a second developer carrier having an elastic surface, and contacting the first developer carrier while biting into it by a predetermined amount. The developer is provided with a preselected degree of fluidity. Hence, even when the same portion of the surface of the second developer carrier runs a plurality of times past a position where the two developer carriers contact each other without any developer being fed from the second developer carrier to an image carrier, the first developer carrier can surely strip the developer from the second developer carrier. As a result, a developer on which a predetermined amount of charge is deposited is transferred from the first developer carrier to the second developer carrier. This successfully protects images from defects. Particularly, when the developer has a zinc stearate content of greater than 0.1 wt %, it is possible to prevent the developer from melting and adhering to a member which regulates the developer.

摘要： A developing device for an image forming apparatus and having a relatively hard first developing roller formed with fine N-S magnetic poles on the periphery thereof, and a relatively soft second developing roller for conveying toner electrostatically transferred thereto from the first roller toward a photoconductive drum. The toner is charged by friction while being passed through between the first roller and a blade, and then magnetically deposited on the first roller. At a position where the first and second rollers contact each other, the adequately charged toner is substantially evenly charged by friction and electrostatically transferred from the first roller to the second roller. The second roller conveys the toner toward the drum. The second roller has a surface roughness whose ratio to the mean particle size of the toner is selected to be less than or equal to 1.5.

摘要： A sheet feeding device for feeding sheets from a tray one by one and an image forming apparatus having the same are disclosed. A tray loaded with a stack of sheets, a separating member for separating a sheet paid out from the tray from the other sheets, and a driven conveyor roller are sequentially arranged around a single pick-up roller. With this arrangement, it is possible to reduce to a load to act on the sheet being conveyed by the pick-up roller and conveyor roller, and to prevent accidental continuous feed or simultaneous feed of a plurality of sheets.

摘要： In an image forming apparatus using a corona discharge type charging device and a contact type image transferring device, a toner deposited on a photoconductive element in the form of a black stripe is prevented from being transferred to the image transferring device; otherwise, the toner would be transferred from the image transferring device to the rear of the following recording medium. Because the toner forming the black stripe is limited to the toner charged to a polarity opposite to an expected polarity, toner consumption ascribable to the stripe is reduced.

摘要： An optical scanning device includes a polygon mirror, a beam detector, a correcting unit, and a controller. The polygon mirror deflects and scans a light beam in a main scanning direction on a surface of an image carrier. The beam detector detects a beam position of the deflected light beam in a sub-scanning direction. The correcting unit calculates a correction amount of out-of-color registration based on the beam position, and corrects out-of-color registration in the sub-scanning direction based on the correction amount. The controller controls, during correction of out-of-color registration, a deflection speed of the deflector to be less than a deflection speed for writing a latent image on the surface of the image carrier.
