いる。[Problems to be Solved by the Invention] By the way, the heating drum is made of aluminum material, and its outer peripheral surface (pressing surface of the endless pressure welding belt) is coated with Teflon or coated with an oxide film (so-called (anodized aluminum). For this reason,
Even if a heat-developable photosensitive material or an image-receiving material coated with water as an image-forming solvent is wrapped around it, it will not corrode.
しかしながら、前述の如く加熱ドラムの外周面に表面処

おいて）重ね合わされる熱現像感光材料と受像材料は、
重ね合わせ時点において波状のシワが発生した。However, since the outer circumferential surface of the heating drum was subjected to surface treatment as described above, this outer circumferential surface had an extremely low coefficient of friction and became slippery. On the other hand, since the overlapping roller is made of rubber and has a large friction coefficient, the photothermographic material and the image-receiving material overlapped by the overlapping roller (between the overlapping roller and the outer peripheral surface of the heating drum).
Wavy wrinkles occurred at the time of overlapping.
このため、熱現像感光材料に記録された画像を受像材料
へ転写する際に現像転写ムラを生じることになり、良好
な画像が得られない場合がある。For this reason, when an image recorded on a heat-developable photosensitive material is transferred to an image-receiving material, uneven development and transfer occurs, and a good image may not be obtained.

ることが目的である。In consideration of the above-mentioned facts, the present invention makes it possible to uniformly overlap the image-exposed photothermographic material and the image-receiving material and wrap them around the outer periphery of the drum, thereby producing a good image without causing uneven development transfer. The purpose is to obtain a thermal development transfer device that can obtain the following.

覆している。[Means for Solving the Problems] A thermal development transfer device according to the present invention superimposes an image-receiving material and a heat-developable photosensitive material arranged on the outer periphery of a drum and having an image exposed thereon by sandwiching the image-receiving material between the drum. A superimposing roller that supplies the photothermographic material and the image receiving material to the outer circumference of the drum, and a pressure contact means that wraps and presses the supplied photothermographic material and image receiving material around the outer circumference of the drum, and heats the supplied photothermographic material and image receiving material in the wound state to thermally develop the material. This is a thermal development transfer device that thermally develops a photosensitive material and transfers an image to an image-receiving material, in which at least an image area on the outer peripheral surface of the drum is covered with a rubber material having a friction coefficient μ of 0.5 or more.

。[Function] In the thermal development transfer device having the above configuration, the photothermographic material on which the image has been exposed is sandwiched between the overlapping roller and the drum, thereby being overlaid on the image-receiving material. Furthermore, the photothermographic material and the image receiving material that have been superimposed are wound around the outer periphery of the drum while remaining in the superimposed state.
その後、ドラムによって加熱され熱現像感光材料が熱現

擦係数μが０．５以上のゴム材によって被覆されており
、重ね合わせローラとにより熱現像感光材料と受像材料
を挟持する際に滑りがなく均一に重ね合わせることがで
き、シワが発生することがなくなる。In this case, at least the image area on the outer peripheral surface of the drum is covered with a rubber material having a friction coefficient μ of 0.5 or more, so that there is no slippage when the photothermographic material and image receiving material are sandwiched between the overlapping rollers. They can be layered evenly and wrinkles will not occur.
したがって各材料を重ね合わせてドラムの外周へ供給し
た後に加熱しこれによって熱現像すると共に画像を転写

が得られる。Therefore, when each material is superimposed and supplied to the outer periphery of the drum and then heated, thereby thermally developed and an image is transferred, a good image can be obtained without uneven development and transfer.

必要な放熱が無くなり、より一層効果的である。Furthermore, the covering range of the rubber material is set such that the dimension along the axial direction of the drum is shorter than the widthwise dimension of the photothermographic material and longer than the widthwise dimension of the exposed image, and is made to cover the entire circumference of the drum. By arranging a peeling claw that peels off the heat-developable photosensitive material and image-receiving material wrapped around the outer circumference of the drum on the outside of this covering area, wear of the rubber material is eliminated and there is no problem in the image area. This eliminates the need for heat radiation, making it even more effective.

３４の外周から剥離させる。After the transfer, a peeling claw 48 moves with the heating drum 34 and engages with the photothermographic material 16 located inside, thereby peeling the photothermographic material 16 together with the image-receiving material 32 from the outer periphery of the heating drum 34.

転写ムラを生じることがなくより一層効果的である。In this case, since the peeling claws 48 are arranged so as to correspond to the outside of the area covered by the silicone rubber 50 on the outer circumferential surface of the heating drum 34 (in other words, the tip ends are located on the outer circumferential surface of both ends of the heating drum 340 in the width direction). (Because they are only in contact and do not interfere with the silicone rubber 50), the silicone rubber 50 is not worn out, and durability is improved. Furthermore, unnecessary heat dissipation caused by the contact of the peeling claw 48 in the image area is eliminated (that is, heating is uniformly performed), and uneven development and transfer does not occur, making it even more effective.

It is separated from the photothermographic material 16 by a conveyor belt 52 wrapped around a separation roller 50 and taken out to a takeout tray 56 via a heater 54 . On the other hand, the heat-developable photosensitive material 16 is sent to a waste photosensitive material storage box 59.
［発明の効果コ
本発明に係る熱現像転写装置は、以下の効果を有してい
