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： An object of the present invention is to prevent an electrical breakdown of a toner layer and an occurrence of overcurrent, thereby preventing quality of image from being degraded at the time of development, when development with one-component toner is conducted using a developing roller of low resistance. The resistance value Rd of a developing roller which carries and conveys one-component toner in a manner of coming into contact with a photoconductor which bears an electrostatic latent image, is defined as Rd=.rho.d.multidot.(Dd1/S1), wherein S1 (cm.sup.2) is an area in which the developing roller comes into contact with the static image bearing member via a toner layer, Dd1 (cm) is a layer thickness of a semiconductive layer which composes the developing roller, and .rho.d (.OMEGA..multidot.cm) is a volume resistivity thereof. The range of the resistance Rd is set as 10.sup.4 5.times.10.sup.7. By using the developing roller of low resistance, excellent development is realized and an electrical breakdown and an overcurrent can be avoided by the resistance value of the toner layer.

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。

摘要： An apparatus having a plurality of replaceable parts. Replaceable parts to which the same life is assigned beforehand are replaced at the same time by hand or by use of a jig. Lives which are integral multiples of the shortest life which one of the replaceable parts has each is assigned to respective one of the other replaceable parts. Hence, when the life of a certain part has expired, the part having the shortest life is automatically replaced together with the part whose life has expired. The replaceable parts each is mounted on and locked to the apparatus and, when the life thereof has expired, unlocked from the apparatus. The expiration of the life is detected either electrically or mechanically, and the parts reached the end of the life is indicated. Before the life of a replaceable part expires, a spare part for replacing it is prepared by detecting that the life is about to expire. The deterioration of a part having a comparatively long life is measured to correct the time for replacing it.

摘要： A developing unit incorporated in an image forming apparatus and having a waste toner container for collecting a waste toner and a fresh toner container containing a fresh toner and adjoining the waste toner container. When the waste toner container is filled with the waste toner, the developing unit causes the waste toner to enter the fresh toner container while preventing the fresh toner from entering the waste toner container. A wall separates the waste toner and fresh toner containers from each other and is formed with an opening. A shutter is associated with the opening and opens when the pressure inside the waste toner container increases due to the waste toner. The waste toner which enters the fresh toner container via the opening is agitated together with the fresh toner as far as possible and then fed to a developing roller or is collected in a container whose volume is variable.
