Abstract:
1. An image forming apparatus, comprising: an image support member configured to support a toner image; a transfer member configured to transfer the toner image on the image supported member onto a continuous web, the transfer member arranged to be rotationally driven and movable towards and away from the image support member; a charger configured to charge a surface of the transfer member; a controller configured to control a position of the transfer member relative to the image support member such that the transfer member is away from the image support member when not printing, and the transfer member is moved towards the image support member when printing such that the continuous web is sandwiched between the image support member and the transfer member, and the controller is configured to control a rotation of the transfer member such that the transfer member is rotated prior to the continuous web being sandwiched, wherein the transfer member comprises: a roller which contacts and is configured to be driven by the continuous web, and is further configured to be driven by rotation occurring within the transfer member due to frictional contact with the roller, wherein the rotating of the roller is switched from being driven by a motor to being driven by the moment of the web when the speed of the continuous web and transfer roller is stable.
