Title: Transfer recorder
Inventor: SATO MASA
IPC: B41J31/14
Filed: 1985-09-03
Abstract: PURPOSE:To provide the transfer recorder in the head of which no heat is stored and which does not leak information, by establishing the recording head capable of selectively applying current to the heating layer of a rotary belt according to the picture information and the ink supply means feeding transfer ink to the rotary belt. CONSTITUTION:The arrangement of an ink supply means 9 is as follows. The ink roller 9a obtained by solidifying transfer ink cylindrically is, in a rotary free state, touched onto the surface of rotary belt 1 by a specific pressure, and an ink head 9b is touched to the heating layer 1a part of the touched rotary belt. As the rotary belt 1 revolves in the arrow marked (a) direction, current flows from a recording electrode 6a to a return circuit electrode 8 via the heating layer 1a and a conductive layer 1b according to the picture information. At that time, because the current density of minute recording electrode 6a part rises, the heating layer 1a in contact with the recording head 6 generates heat according to the picture information. The transfer ink layer 5 formed on the rotary belt 1 is fused by this generation of heat and the picture information is transferred onto a recording sheet 2. Because the heating layer 6a which generated heat is revolving away, the recording head 6 part does never store heat.
