摘要： The object of the invention is to certainly remove and certainly recover the charged toner remaining on a developing roller after development. A single component toner which is delivered to the developing roller via a toner-supplying roller is made into a relatively thin layer of a predetermined thickness with a charging plate and is frictionally charged with a given quantity of electric charge. Subsequently, the toner is adhered on a photoreceptor drum along by the electrostatic latent image to develop an image at the developing region at which the developing roller comes into contact with the photoreceptor drum. After development, the electric charge of the toner layer on the developing roller is removed with an electric-charge-removing sheet. The toner after development is recovered into a toner hopper via the toner-supplying roller. In rotation direction of the developing roller, the relation of the width Wt of the toner layer to the width Wc of the electric-charge-removing sheet is established so as to be Wc.gtoreq.Wt. Thus, the electric charge of the toner layer on the developing roller is certainly removed.

摘要： A blade is pressed against a developing roller for regulating the amount of toner which is deposited on a surface of the developing roller. The blade is formed with a slant face at its tip end, to which the toner is transported along a direction of rotation of the developing roller. An angle of aperture .theta. at a toner inlet portion defined by the developing roller and the slant face is set at 12.5.degree. or more, the angle of aperture counting in an angle .psi. of the slant face, elastic deformation and radius (R) of the developing roller, and an angle .alpha. related to a nip width w on which the blade contacts with the developing roller. Such an angle of aperture .theta. provides a great allowance for a free length l of the blade, thereby permitting the blade to maintain a constant toner mass for forming a uniform toner layer.

摘要： In a mono component toner developing device, a developing roller supporting and conveying the mono component toner is arranged in contact with a photoreceptor supporting a static latent image. A supplying roller is arranged opposing the developing roller with a predetermined contact depth. The supplying roller has a pair of driven gears fixed at both ends of the rotational shaft thereof for being rotated so as to be meshed with a pair of driving gears rotated by a driving motor. The rotational force of the driving gears, acting at a coupling position, is used to deflect the supplying roller toward the developing roller side, whereby the supplying roller is pressed in approximately uniform contact with the developing roller across its full length along the shaft.

摘要： A developing apparatus includes a toner carrier for transferring toner to a development position, a layer-thickness regulating member for forming a toner layer having a predetermined thickness on the toner carrier by making contact in a leading edge or a surface of a vicinity of the leading edge with the toner carrier, and a supplier for supplying a one-component toner to the toner carrier. Also combined with the layer-thickness layer is a vibration absorbing device allowing the toner to be applied in a uniform thickness. The vibration absorbing device can also be a sealing member located on the toner carrier. Each sealing member can be two different materials effective to absorb vibration.

摘要： To prevent scattering of toner when an image forming operation is started and ended in a developing process using one-component toner, a rotatable developing roller in contact with a photosensitive member carrying a static latent image, which is used to carry and feed one-component toner, is provided in a developing tank containing one-component toner. Initially, toner is fed to a feed roller, then passed through a toner restricting member which is pressed against the developing roller to restrict the amount of toner to be fed, so that a layer of toner is formed at a fixed thickness and fed into a developing area in contact with the photosensitive member. Thus a static latent image is produced on the developing roller. In this process, a developing bias voltage Va is supplied to the developing roller, a restricting voltage Vb is supplied to the toner restricting member so as to fix the thickness of the toner layer, and a supply voltage Vc is supplied to the feed roller to control the supply of toner. Specifically, the developing bias voltage Va, restricting voltage Vb, and supply voltage Vc are applied to their respective objects before the developing roller begins rotating, thereby minimizing or preventing the scattering or blowing out of toner. Additionally, supply of those voltages Va, Vo, and Vc are stopped after the developing roller stops, which also helps to prevent excess scattering of toner.
摘要翻译：为了防止在使用单组分调色剂的显影过程中开始图像形成操作并结束时调色剂的散射，可旋转的显影辊与携带静电潜像的感光部件接触，该感光部件用于承载和供给单组分调色剂调色剂设置在含有单组分调色剂的显影槽中。最初，将调色剂送入进料辊，然后通过调色剂限制部件，该调色剂限制部件被压靠在显影辊上，以限制要供给的调色剂的量，使得一层调色剂以固定的厚度形成并供给到显影区域与感光构件接触。因此，在显影辊上产生静电潜像。在该过程中，向显影辊供给显影偏压Va，将限制电压Vb提供给调色剂限制件，以固定调色剂层的厚度，并将供给电压Vc供给到进料辊控制墨粉的供应。具体地说，在显影辊开始旋转之前，将显影偏压Va，限制电压Vb和电源电压Vc施加到它们各自的物体上，从而最小化或防止调色剂的散射或吹出。此外，在显影辊停止之后，停止提供这些电压Va，Vo和Vc，这也有助于防止调色剂的过度散射。
