    摘要： An image forming apparatus including a latent image carrier and a developing device for charging a toner into a negative polarity by triboelectric charging, wherein the work function of the toner is set to be larger than the work function of the surface of the latent image carrier. When the apparatus includes an intermediate transfer medium, the work function of the toner is set to be larger than the work function of the surface of the intermediate transfer medium. In another embodiment, the work function &PHgr;opc of the surface of the latent image carrier, the work function &PHgr;t of the toner, and the work function &PHgr;TM of the surface of the intermediate transfer medium are set to satisfy a relationship &PHgr;t>&PHgr;OPC>&PHgr;TM. These relationships help to reduce fog, and improve transfer efficiency which reduces the consumption of the toner.

    摘要： A looped belt is stretched by a drive roller and a driven roller and circulated therearound. The driven roller is capable of functioning as a regulation roller for regulating meander action in the belt. Each of image formers forms a toner image associated with each single color constituting a color image. Transferring members are disposed on a circulating path of the belt member. Each transferring member is associated with each image former for transferring the toner image onto either the belt member or a recording medium held on the belt member. A cleaning blade is abutted against a part of the belt member wound on the drive roller for removing toner remained on the belt member after the toner image transfer is performed.

    摘要： In a color image forming apparatus, a looped belt member is stretched and circulated by at least a drive roller and a driven roller so as to have a tensed side and a slack side. Each of plural image supporting members supports a single color toner image thereon, and abuts onto the tensed side of the belt member to define a transferring position at which the toner image is transferred onto either the belt member or a recording medium held by the belt member, while being rotated. A circumferential velocity of each image supporting member is determined so as to be lower than a circulation velocity of the belt member. Further, a circumferential velocity of an image supporting member which is further from the driving roller may be lower than a circumferential velocity of an image supporting member which is closer to the driving roller.

    摘要： A color image forming apparatus includes a primary transport system for moving a photosensitive receiving member of continuous length, which is designed to receive the exposure of an original image to be reproduced forming a latent image of the original at an exposure station. The photosensitive receiving member is transported through the exposure station at a maintained constant rate of movement while assuring the transport of the photosensitive receiving member through downstream stations, involving development of the latent image and transfer of the developed image to an image receiving medium, is accomplished without causing slack, wrinkling or jamming of the photosensitive receiving member in the apparatus or distortion of the developed image during its transfer to an image receiving medium. The control of the transport of the photosensitive receiving member through the apparatus may be accomplished with a combination of a primary transport system and a secondary transport system respectively positioned in the region of the pressure transfer section and downstream of the exposure station to transport the photosensitive receiving member at different rates of movement. Conflict due to different transport rates applied to the photosensitive receiving member is eliminated by establishing a differential motion buffer in the transport path between the primary transport system and the secondary transport system. In this connection, the differential motion buffer provides for slack compensation or tension biasing in conjunction with any slack developed in the transport of the photosensitive receiving member through the apparatus.

    摘要翻译： 彩色图像形成装置包括用于移动连续长度的感光接收构件的主传送系统，其被设计为在曝光站处接收形成原稿的潜像的要再现的原始图像的曝光。 感光接收构件以保持恒定的运动速度传送通过曝光站，同时确保感光接收构件通过下游站的传输，涉及潜像的显影和显影图像的传送到图像接收介质。 不会使感光接收构件在设备中松弛，起皱或卡住，或者在显影图像传送到图像接收介质期间变形。 通过装置控制感光接收构件的传送可以通过分别位于压力传送部分和曝光站下游的主传送系统和辅助传送系统的组合来实现，以便将感光接收 会员不同运动速度。 通过在主输送系统和二次输送系统之间的传送路径中建立差动运动缓冲器来消除由于施加到感光接收部件的不同运送速率的冲突。 在这方面，差动运动缓冲器与通过装置的光敏接收构件的传送中产生的任何松弛相结合，提供松弛补偿或张力偏置。
