ABSTRACT:
A transfer device used in an electrophotographic recorder capable of effectively prevent paper jamming and transfer missing in a transfer process which comprises a guide member of an insulating material disposed at a downstream side wall end of a casing and an insulating member of current interruption disposed at an upstream side wall end of the casing, in which the guide member, even when subjected to heat, stably keeps its rigidly mounted state and prevents the falling of the paper into an opening of the casing, and the insulating member of current interruption minimizes the flow of a transfer current from a charging wire toward a small-diameter rubber roller to prevent the transfer missing.
