In general, an electrostatic or electrophotographic transfer type image recording device (K%2) uses toner to transfer ms onto recording paper (plain paper) in a transfer section. However, due to the residual charge on the surface of the recording medium after transfer, an electrostatic attraction force acts on the recording paper, and it does not separate from the surface of the recording medium, so some method is taken to force the recording paper after transfer from the surface of the recording medium. target (needs to be separated)

Conventionally, a separating claw has been used as a means for separating the recording paper from the surface of the recording medium after transfer. In the case of an endless belt stretched over a belt, there is a possibility that the belt may be damaged by the separating claw due to minute vibrations generated during rotational movement, so it cannot be applied.

As shown in the figure, the recording medium 2 is bent from the point K where the recording medium 2 is bent along the roller 1 (a transfer section is provided, and the recording paper 3 that is sluggish after the transfer has its own stiffness and elasticity). Although it is designed to be separated naturally from the surface and transported upward, it is difficult to separate it when using the recording paper 3, which has a weak stiffness, and even after the transfer, the recording is carried out by electrostatic attraction force. The paper 3 sticks to the recording medium 21iK and is conveyed in one direction, causing a jam.*rjg In the figure, 4 indicates the corona discharger for transfer, and S indicates the guide plate for the recording paper 3. .

The present invention has been made in consideration of the above points, and in particular, it is a transfer type recording device (2) using an endless belt-shaped recording medium to easily and reliably separate the recording paper after transfer. In the following, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the recording paper separation method according to the present invention, as shown in FIG. 2 and FIG.
In order to prevent the small diameter roller 6 from deflecting due to the tension between the recording medium 2 and the small diameter roller 6 that guides the conveyance of the Al11IIsvc recording medium 2, the roller 6 rotates in contact with the inside of the roller 6. Auxiliary roller 7 with a relatively large diameter
By providing a roller pair consisting of K, the bending radius of the roller pair portion VC of the recording medium 2 is made small, and after transfer! The paper 3 is designed so that it can be separated from the two prints of the recording medium due to its own elasticity. For example, the small roller @1 and the auxiliary roller 7 are made of stainless steel or a stainless steel shaft (a roller coated with conductive treated rubber).
The auxiliary roller 7 is rotated according to the rotation of the small diameter roller 6 that guides the recording medium 2.

According to the recording paper separation method according to the present invention, even when a weak recording paper 3 is used, the free radius of the recording medium 20 in the transfer area is small (ξ)
Since the distance is steep, the recording paper 3 can be separated from the two surfaces of the recording medium at C**, and the occurrence of jam can be effectively prevented.
