Abstract
Abstract An image transfer device in an image forming apparatus is generally constructed with a recording element as an intermediate recording medium to hold thereon an image to be transferred onto an image transfer material. An image transfer device transfers the image from the recording element to the image transfer material and a guiding device guides the image transfer material which is capable of setting a position from the recording element in accordance with a kind of the image transfer material used. An image transfer material conveying device conveys the image transfer material through the recording element and the image transfer device and driving device displaces the guiding device in the direction away from the recording element at the time of non-operation of the image transfer material conveying device.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
203 words
An image transfer device for transferring an image from an information recording element, said device comprising: means for transferring an image from the information recording element to a transfer material, at an image transfer station; means for feeding the transfer material to said transfer means; symmetrically arranged transfer material guiding members extending along a transfer material path, each having a first end portion which is remote from said transfer means and a second end portion which is near said transfer means, said first end portion being pivotable to allow the setting, in accordance with the thickness of the transfer material, of the distance between the second end portion and the information recording element at the image transfer station; driving means, engaged with each of said guiding members adjacent the second end portion thereof, for moving only the second end portions away from the recording element, wherein each guiding member, when said feeding means is not in operation, is away from the information recording element; and biasing means for applying resilient tension to the transfer material to ensure that the transfer material is spaced apart from the information recording element when said driving means moves said guiding members away from the information recording element.
