PROBLEM TO BE SOLVED: To provide an imaging drum which can fix a sheet material even when the drum is rotated at a high speed. SOLUTION: An imaging drum assembling body used for an imaging device for forming an image on a sheet material 36 includes a rotating imaging drum, and the imaging drum has an outer face 38 adapted so that the sheet material 36 is drawn. A material clamp 50 is mounted on the imaging drum and has a fixture 52 for positioning a fixing face 56 radially outward from the outer face 38, and a space is formed between the outer face 38 and the fixing face 56. A slide 66 is arranged movable in a space between a fixing face 52 which stops the slide 66 at a position of the radial outward to prevent it from going further outward and a position of the radial inward away from the fixing face 52, and the slide 66 is energized toward the position of radial outward by an energizing member.
