ABSTRACT:
An improved transfer apparatus for use for example in an electrostatographic reproduction device wherein marking particle images are transferred from a moving transferable image support by a transfer member as the transfer member moves in contact with the support. The improved transfer apparatus includes a drive for moving the transfer member at a predetermined speed substantially in timed relation with movement of the transferable image support. A mechanism, located between the transfer member and the drive, accommodates for any mismatch in speeds of the transfer member and the support at the area of contact therebetween. A member, located in that portion of the transfer member outside of the image transfer area, facilitates relative movement between the transfer member and the support during the period of time when the facilitating member is in intimate contact with the support, whereby the transfer member is substantially decoupled from the transferable image support such that any force buildup due to speed mismatch is relieved to enable registration between the transfer member and the support to be periodically reset.
