摘要： In an image forming apparatus, a device for supporting a photoconductive element or image carrier includes an implementation which allows the element to be rapidly and easily dismounted from the apparatus together with its shaft, i.e., without having the shaft pulled out or inserted. Therefore, the device enhances easy replacement of the photoconductive element. The operation is simple because the photoconductive element and shaft do not have to be handled independently of each other.

摘要： In an electrophotographic image forming apparatus of the type using single-ingredient type high resistance toner, a developing roller or similar toner conveyor roller is covered with a dielectric layer which is comparatively thick at opposite end portions than at an intermediate portion. A conductive or semiconductive elastic layer underlies the dielectric layer. With the above configuration, the dielectric layer is prevented from coming off the roller. This, coupled with the fact that the elastic layer does not contact a photoconductive element, eliminates current leaks and thereby extends the life of the roller and photoconductive element.
摘要翻译：在使用单成分型高电阻调色剂的电子照相图像形成装置中，显影辊或类似调色剂输送辊被相对端部比在中间部分相对较厚的电介质层覆盖。导电或半导电弹性层位于介电层的下面。通过上述结构，可以防止电介质层脱落。这与弹性层不接触感光元件的事实相结合，消除了电流泄漏，从而延长了辊和光电导元件的使用寿命。

摘要： An image forming apparatus including a developing device having various components with specific relationships between their lengths. There is an image bearing member such as a photoconductive drum or belt having a photosensitive layer. The photosensitive layer has a length A. A first toner transporting roller has two ends, the length between the two ends being defined as B. Additionally, there is a second toner transporting roller, disposed between and contacting both the image bearing member and the first toner transporting roller. The length of the second toner transporting roller being defined as C. The components of the image forming apparatus are constructed such the length of the second toner transporting roller is less than or equal to the lengths of both the first toner transporting roller and the photosensitive layer of the image bearing member. This means that the relationships A>C and B>C may exist. As an alternative, B is approximately equal to C with A being greater than both B and C. As a further alternative, A, B and C are each approximately equal to each other.

摘要： In an image forming apparatus, a developing device operable with toner or single component type developer has a hard first developing roller and a soft second developing roller. Fine magnetic N-S poles are formed on the periphery of the first roller. The second roller conveys the toner, electrostatically transferred thereto from the first roller, to an image carrier. The device frees a toner image from deterioration due to toner particles charged to a polarity opposite to an expected polarity. The toner forms a uniform thin layer on the first roller and is uniformly charged. Toner for use with this type of developing device is also disclosed.

摘要： In an image forming apparatus, a developing device of the type developing an electrostatic latent image formed on an image carrier by using single-component type toner has a regulating member for regulating the amount of the toner fed thereto, a first conveying member for conveying the toner regulated by the regulating member and deposited thereon, and a second conveying member for conveying the toner transferred from the first conveying member thereto to the image carrier. The first and second conveying members are each movable at a particular speed in a particular direction.

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, only the adequately charged toner is electrostatically transferred from the first roller to the second roller. The second roller conveys the toner toward the drum. As a result, the toner is brought to a developing position in an amount corresponding to a saturation or maximum image density. The second roller is made up of a metallic conductive core, a semiconductive foam layer, and an insulative surface layer implemented by resin. The real resistance between the core and the surface is selected to be higher than 10.sup.3 .OMEGA. but lower than 10.sup.13 .OMEGA.. The ratio of the real resistance associated with the maximum temperature change to the real resistance at normal temperature is selected to be less than or equal to 4 in absolute value.

摘要： An image forming apparatus includes an image carrier, a cleaning device having a cleaning member that comes into contact with a surface of the image carrier, and a lubricant applying device provided on the downstream side of the cleaning member. The lubricant applying device includes a solid lubricant, a lubricant supply roller, and a trailing type lubricant smoothing blade that is provided on the downstream side of the lubricant supply roller, and comes into belly contact with the surface of the image carrier. After image carrier is stopped, constantly or under a predetermined condition, the surface of the image carrier is moved in a direction opposite to an image forming direction. The opposite movement distance is equal to or more than the shortest distance between a contact point between the lubricant supply roller and the image carrier and a contact point between the lubricant smoothing blade and the image carrier.
