Intermediate transfer unit comprising a control circuit for stabilizing the bias potential for transferring a toner image from a photosensitive drum to an intermediate transfer belt against current variations caused by simultaneous transfer of a toner image from the intermediate transfer belt to a copy paper
摘要：
The present invention provides an intermediate transfer unit, comprising a photoconductive drum, an intermediate transfer belt, a primary transfer member, which primarily transfers a toner image formed on said photoconductive drum onto said intermediate transfer belt at a primary transfer position, said primary transfer member having a resistance value (RT) of 1 MΩ or less, a secondary transfer member, which secondarily transfers said toner image from said intermediate transfer belt to a recording medium, an elastic backup member disposed in said primary transfer position, and a high-voltage power source (V 1 ), which applies bias to said primary transfer member under a current absorbable constant-voltage control (R X ).
摘要（中）：

本发明涉及到在中间转印单元，包括：中间转印带（360），以将形成在感光鼓上（110）的调色剂图像被一次转印和所述调色剂图像二次转印到记录介质（S），和 驱动辊（310），用于循环所述中间转印带（360），其具有一个关节。 在此，中间转印单元的初级转印位置，其中，所述调色剂图像被一次转印，被布置为靠近所述驱动辊（310）。 中间转印单元还包括：一次转印部件（320），用于主要传递环形成在感光鼓（110）上的调色剂图像，和二次转印辊（380），用于二次转印环的调色剂图像定影在记录介质（S） ， 当没有图像被形成，以在将调色剂从二次转印辊（380），以在中间转印带返回的方向的电场（360）被形成，而在二次转印辊（380）上的中间转印带按压 （360），并且当所述中间转印带（360）的接合是相对的二次转印辊（380），二次转印辊（380）从所述中间转印带（360）分离。
