摘要： A developing unit includes a developing hopper, a toner reserve container that incorporates a replenishing roller and a replenishing port forming a toner replenishing portion, arranged adjacent to the developing hopper in order to supply the toner to the developing hopper. The toner reserve container further includes an agitator rotatable about a rotary shaft and a conveying sheet attached to the agitator for conveying the toner to the replenishing roller. The conveying sheet has a bent portion where the conveying sheet is bent in the rotational direction of the agitator at a halfway point thereof with a predetermined angle &agr;. Deformation of the conveying sheet during rotation is absorbed around the position of the bent portion, so that the conveying sheet will not be plastically deformed at the attached part of the conveying sheet joined to the attachment edge of the agitator, whereby long stable toner conveyance by the conveying sheet can be maintained.

摘要： A toner reserve container provided with a toner replenishing roller and a replenishing port which constitute a toner replenishing portion is arranged adjacent to a developing hopper and is provided with a toner conveying unit. The conveying unit includes an agitator rotated about a rotary shaft and a conveying sheet fixed to the agitator and scooping up and conveying toner to the toner replenishing roller. The conveying sheet has a plurality of slits formed close to the end portion where it is fixed to the agitator and extending in the direction from the end portion to the tip end of the conveying sheet. When the conveying sheet is rotated and deformed, the plurality of slits absorb rotational load to keep toner conveyed by the conveying sheet stable for a long period of time.

摘要： An object of the invention is to transport safely and reliably a unit such as a developing cartridge in which toner is used, and toner, and to reduce the dimensions and cost of an apparatus for packaging such a unit. Two buffer members are fixed to two opposite widthwise end sides of a developing cartridge, and the resultant combination is accommodated in a packaging box. Each buffer member has a hollow structure formed by blow molding a thermoplastic resin material. The toner is inserted into the interior of each buffer member from an opening thereof, and the buffer members and a non-toner-charged developing cartridge can be packaged together and transported. When the toner in each buffer member is supplied via the opening thereof to the interior of the developing cartridge after the transportation of these parts is completed, a structure in the developing cartridge for preventing the coagulation and leakage of the toner being transported can be simplified, and cost reduction can be effected. Since dead space in the packaging box is effectively utilized for the transportation of the toner, the safety of the transportation and a decrease in cost can be attained.
摘要翻译：本发明的目的是安全可靠地运输诸如使用调色剂的显影盒和调色剂之类的单元，并且减小用于包装这种单元的装置的尺寸和成本。两个缓冲构件固定在显影盒的两个相对的横向端侧，并且所得到的组合被容纳在包装盒中。每个缓冲构件具有通过吹塑热塑性树脂材料形成的中空结构。调色剂从其开口插入每个缓冲构件的内部，并且缓冲构件和非调色剂充电的显影盒可以包装在一起并运输。当在完成这些部件的输送之后，将每个缓冲构件中的调色剂经由其开口供应到显影盒的内部时，可以简化显影盒中用于防止被输送的调色剂的凝结和泄漏的结构，并且可以实现成本降低。由于包装盒中的死空间有效地用于调色剂的输送，因此可以实现运输的安全性和成本的降低。

摘要： A toner image fixing device comprises a heat roller and a lamp heater. The lamp heater is formed from a nicrome wire stretched between clamp terminals, a silica tube and ceramic holders closely fitted to respective ends of the silica tube and which have an external diameter which is substantially the same as the diameter of the heating roller. The lamp heater is secured by a lamp holder and frame to the shaft of the heat roller. The heat roller is rotatably supported by a bearing and is driven by a driving gear.

摘要： A developer cartridge for image forming apparatuses which performs development to form images with non-magnetic, one-component type developer. The cartridge includes a developing roller for supplying developer to a photoconductor drum, a developer feed roller in non-contact with the developing roller for supply developer to the developing roller, and a developer-layer thickness control member for controlling the thickness of the developer layer on the developing roller. The developer feed roller is shaped as a regular polygonal prism. Since no recesses are formed in the surface of the regular polygonal prism, driving torque does not increase when developer is scrubbed from the prism, thus ensuring consistent operation and improved image quality. Non-magnetic, one-component type developer is compressed onto the developing roller by supplying the developer via the developer feed roller into a bottleneck between the developing roller and a developer applying member. The amount of developer which passes through the bottleneck onto the developing roller is controlled by a temporary reservoir, the pressurization thereof ensuring application of the developer to the developing roller. A control roller may be used against the developing roller to lower friction of developer, thereby preventing deposition of developer on the control roller while establishing a consistent amount of developer on the developing roller.
摘要翻译：用于图像形成装置的显影剂盒，其用非磁性单组分型显影剂进行显影以形成图像。盒包括用于将显影剂供应到感光鼓的显影辊，与用于向显影辊供应显影剂的显影辊非接触的显影剂供给辊以及用于控制显影剂层厚度的显影剂层厚度控制部件在显影辊上。显影剂供给辊的形状为正多边形棱镜。由于在正多边形棱镜的表面没有形成凹部，所以当从棱镜上洗涤显影剂时，驱动扭矩不会增加，从而确保一致的操作和改进的图像质量。通过将显影剂通过显影剂供给辊供给到显影辊和显影剂施加构件之间的瓶颈中，非磁性的单组分型显影剂被压缩到显影辊上。通过瓶颈到显影辊上的显影剂的量由临时储存器控制，其加压确保将显影剂施加到显影辊上。可以使用控制辊抵靠显影辊以降低显影剂的摩擦，从而防止显影剂在控制辊上沉积，同时在显影辊上建立一致量的显影剂。

摘要： An electrophotography developing apparatus has been developed which can protect a developer holder and a layer thickness control member from damage. The device also prevents internal scattering of the developer while preventing a surplus supply of the developer to both ends on the peripheral surface of the developer holder. The unique advantages of the invention are derived through the utilization of sealing members having different elastic properties, which assume both bulk removal of excess developer while providing the needed uniform developer thickness. Another embodiment of the invention has the width of the layer thickness control member in a longitudinal direction set wider than the width of the developer holder in a longitudinal direction, and both side edges of the layer thickness control member are positioned outside both side edges of the developer holder. Proper sealing is assured by having the inner side edges of the sealing member positioned inside the side edges of the developer holder and outside the side edges of the image area of the image holder.
