摘要： An image transfer member, an image transfer device and an image forming system employing the image transfer member and device are disclosed. The image transfer member comprises a base layer, and a surface layer formed from a semi-conductive material above the base layer to receive the developer image transferred from the photoconductor. The surface layer forms a contact inscribed angle θ in the range of 10° to 50° between the surface thereof and the developer image. The image transfer member has a voltage-current characteristic exhibiting a current density (CD) in the range of 0.6 μA/cm2≦CD≦1.5 μA/cm2 at 1 KV voltage, and a voltage decay characteristic exhibiting a voltage decay time (DT) in the range of 0.4 sec≦DT≦3 sec for the voltage decay from 500 V to 100 V. The present invention avoids a transfer defect such as transfer void produced by breakdown caused when a high bias voltage is applied to a developer image having a high electric charge and to significantly improve the transfer efficiency.

摘要： An image forming apparatus is provided that forms an image with liquid developer, and a method thereof. The image forming apparatus includes a plurality of photoconductors on which developer images having carrier rates different from each other are formed with corresponding liquid developers. An image transfer member is disposed to form transfer nips with the respective photoconductors in such a manner that the developer images of the respective photoconductors are overlappingly transferred onto the image transfer member according to a transfer order predetermined on the basis of the carrier rates thereof. The developer images from the respective photoconductors are moved to an image receiving medium. Since the developer images formed on the plurality of photoconductors are overlappingly transferred onto the image transfer member according to the predetermined transfer order, the developer images previously transferred at the prior transfer nips are substantially prevented from generating a squeezed carrier beyond a predetermined limit at the posterior transfer nips. The squeezed carrier is substantially prevented from accumulating beyond the predetermined limit at the inlet side of the posterior transfer nips when the developer images are transferred from the respective photoconductors to the image transfer member.
摘要翻译：提供一种用液体显影剂形成图像的图像形成装置及其方法。图像形成装置包括多个感光体，其上具有彼此不同的载流子速率的显影剂图像由相应的液体显影剂形成。图像转印部件设置成与相应的感光体形成转印夹，使得各个感光体的显影剂图像根据其基于载体速率预定的转印顺序重叠地转印到图像转印部件上。来自各个感光体的显影剂图像被移动到图像接收介质。由于形成在多个感光体上的显影剂图像根据预定的转印顺序重叠地转印到图像转印部件上，所以基本上防止了先前在先前转印夹头转印的显影剂图像在后面产生超过预定极限的挤压载体转移夹。当显影剂图像从相应的感光体转印到图像转印部件时，基本上防止挤压的载体积聚超过后转印夹的入口侧的预定极限。
