Abstract

A transfer target object separation apparatus includes: a transfer target object movement member that moves a transfer target object while in contact with a first surface of the transfer target object; and a transfer target object separation suction section that sucks a second surface of the transfer target object opposite the first surface to separate the transfer target object from the transfer target object movement member. The transfer target object separation suction section includes a first cylindrical rotation member that has a suction inlet, and a second cylindrical rotation member that is fitted on the first cylindrical rotation member and has a hole through which the second surface of the transfer target object is sucked.

Claims

1. A transfer target object separation apparatus comprising:

a transfer target object movement member that moves a transfer target object while in contact with a first surface of the transfer target object; and

a transfer target object separation suction section that sucks a second surface of the transfer target object opposite the first surface to separate the transfer target object from the transfer target object movement member, the transfer target object separation suction section including

a first cylindrical rotation member that has a suction inlet, and

a second cylindrical rotation member that is fitted on the first cylindrical rotation member and has a hole through which the second surface of the transfer target object is sucked.

2. The transfer target object separation apparatus according to claim 1, further comprising a vacuuming section that sucks air through the hole of the second cylindrical rotation member.

3. The transfer target object separation apparatus according to claim 1, wherein the first cylindrical rotation member rotates;

and the second cylindrical rotation member rotates independently of the first cylindrical rotation member.

4. A transferring apparatus comprising:

a transferring member that causes a transfer target object to move in contact with an image carrier so as to transfer an image carried on the image carrier onto a first surface of the transfer target object; and

a transfer target object separation suction section that sucks a second surface of the transfer target object opposite the first surface to separate the transfer target object from the image carrier, the transfer target object separation suction section including

a first cylindrical rotation member that has a suction inlet, and

a second cylindrical rotation member that is fitted on the first cylindrical rotation member and has a hole through which the second surface of the transfer target object is sucked.

5. The transferring apparatus according to claim 4, further comprising a vacuuming section that sucks air through the hole of the second cylindrical rotation member.

6. The transferring apparatus according to claim 4, wherein the first cylindrical rotation member rotates;

and the second cylindrical rotation member rotates independently of the first cylindrical rotation member.

7. An image formation apparatus comprising:

a latent image carrier that carries a latent image;

a developing section that develops the latent image with the use of a liquid developer to form an image on the latent image carrier;

a transfer medium onto which the image is transferred;

a first transferring section that transfers the image formed on the latent image carrier onto the transfer medium;

a second transferring section that transfers the image transferred to the transfer medium onto a first surface of a transfer target object; and

a transfer target object separation suction section that sucks a second surface of the transfer target object opposite the first surface to separate the transfer target object from the transfer medium, the transfer target object separation suction section including

a first cylindrical rotation member that has a suction inlet, and

a second cylindrical rotation member that is fitted on the first cylindrical rotation member and has a hole through which the second surface of the transfer target object is sucked.

8. A transfer target object separation control method comprising:

moving a suction inlet of a first cylindrical rotation member to a standby position;

rotating a second cylindrical rotation member that has a hole through which a transfer target object is sucked;

rotating the first cylindrical rotation member to move the suction inlet to a suction position;

evacuating air from the first cylindrical rotation member to suck the transfer target object through the suction inlet of the first cylindrical rotation member and a hole of the second cylindrical rotation member;

rotating the first cylindrical rotation member and the second cylindrical rotation member with the transfer target object being in a sucked state;

stopping the rotation of the first cylindrical rotation member when the suction inlet of the first cylindrical rotation member arrives at a suction release position; and

stopping the rotation of the second cylindrical rotation member when the hole of the second cylindrical rotation member through which the transfer target object is sucked arrives at a position at which suction through the suction inlet of the first cylindrical rotation member is not performed.
