摘要： A sheet member conveying device is equipped with an endless sheet member conveyor belt composed of a semiconductor material and an electrical charging device which electrically charges the sheet member conveyor belt in order to transfer a toner image formed on the surface of a rotary drum onto a sheet member at a toner image transfer position. The sheet member conveyor belt is put around a plurality of rollers and moves from the toner image transfer position toward a sheet member peeling position. A grounding device is provided between the toner image transfer position and the sheet member peeling position along the sheet member conveyor belt in order to decrease the surface potential which is due to the charge of the sheet member conveyor belt.

摘要： This invention relates to an image forming apparatus with a transfer unit for transferring toner electrically to an electrostatic latent image formed on a photoreceptor onto a copy sheet. The image forming apparatus has a transfer electrode charge supply means for supplying electric charges to a transfer electrode provided in the transfer unit to electrically attract the toner onto the copy sheet and control means for controlling the quantity of electric charges to be supplied to the photoreceptor via the transfer electrode from the transfer electrode charge supply means based on a photoreceptor inflow current flowing to the photoreceptor through the charge send/receive means and on a photoreceptor outflow current flowing out from the photoreceptor through a ground wire connecting the photoreceptor and the ground. The charge send/receive means, other than the transfer unit, sends and receives electric charges to and from the photoreceptor. With this arrangement, variation of photoreceptor inflow current due to image density variation of an original document can be controlled to perform a stable image transfer.

摘要： A transfer plate which also serves as a sheet guide plate is pushed by a torsion spring. A minimum gap less than 0.2 mm between a guide surface of the transfer plate and the surface of a photoreceptor drum is maintained to be smaller than the thickness of a transfer sheet by a spacer member provided on the guide surface. When the sheet passes through the gap between the drum surface and the guide surface, the transfer plate is pushed down by the sheet and the sheet is pressed onto a toner image formed on the drum surface with an appropriate pressure by the pushing force of the torsion spring. At this time, a transfer voltage is applied to the transfer plate, so that the toner image on the drum surface is transferred to the sheet.

摘要： An image-transfer and sheet-separating apparatus transfers an image toner-developed from a positive latent image and retained on a photoconductor drum onto a copy sheet, and subsequently separates the sheet from the photoconductor drum. A bias voltage including a sheet peel-separating AC voltage superimposed on an image-transferring DC bias voltage is applied to a transfer roller which presses on the photoconductor drum. A post image-transfer charge-stripping element removes charge from the copy sheet and is disposed in a portion of the sheet-transport stream forward of a nipping position at which the transfer roller presses against the photoconductor drum. Thus, charge remaining on the copy sheet is discharged, ensuring high efficiency in image transfer and accordingly reducing the incidence of failure in the separation of the copy sheet from the photoconductor drum. The bias voltage is within the range of 500 V and 2000 V and specifically, the AC and DC biases are within the range of 1000 V and 1500 V. In addition, the transfer roller is moved toward or away from the photoconductor depending on the thickness of the copy sheet.
摘要翻译：图像转印和片材分离装置将从正潜象调色剂显影的图像转印并保持在感光鼓上到复印纸上，随后将片材与感光鼓分离。将叠加在图像转印直流偏置电压上的片剥离交流电压的偏置电压施加到压电感光鼓上的转印辊上。后图像转印电荷剥离元件从复印纸移除电荷并且将其放置在转印辊压靠在感光鼓上的夹持位置的前方的片材输送流的一部分中。因此，复印纸上剩余的电荷被排出，确保图像转印的高效率，并因此减少了复印纸与感光鼓的分离失败的发生。偏置电压在500V和2000V的范围内，具体地说，AC和DC偏压在1000V和1500V的范围内。此外，转印辊根据厚度移动或离开感光体的副本。
