Conveying device of recording medium and image forming apparatus

An image forming apparatus comprising:

• an endless device which has a circumferential surface, and rotates in a circumferential direction;
• a laminated cover which is arranged in an overlapping manner on the circumferential surface of the endless device including, a metal layer having a surface which comes into contact with the circumferential surface of the endless device, and both end portions and both side portions in the circumferential direction, and a circumferential edge;
• and a dielectric layer which has a surface which comes into contact with the metal layer, and both end portions and both side portions in the circumferential direction, and a circumferential edge, and has extended regions which protrude at least a part of both of the end portions and both of the side portions of the dielectric layer, from the circumferential edge of the metal layer, and follows the circumferential surface of the endless device;
• a rotation mechanism which rotates the endless device in a circumferential direction;
• a supply mechanism which supplies a recording medium to the endless device;
• a charging roller which charges the dielectric layer of the laminated cover to adsorb the recording medium;
• a recording head unit which forms images on the recording medium;
• a separation mechanism which separates the recording medium on which the images are formed, from the dielectric layer;
• and
• a discharge mechanism which discharges the recording medium which is separated from the dielectric layer.
