PURPOSE:To simplify the shape of the flange of an image carrier and to reduce the diameter of the flange by fitting a shaft support hole formed in the flange onto the fitting part of the shaft body of a driving shaft and fitting the recessed part of said hole onto the pin to the shaft body. CONSTITUTION:The image carrier 2 fitted to the housing 13 of the print cartridge A is formed by fitting flanges 41 onto both end parts of a drum 40. Each flange 41 is provided with the shaft support hole 43, which has plural recessed parts 43a in the inner peripheral surface, in the center of its rotation. Further, a fitting pat 46a and a pin 49 are provided at the tip part of the driving shaft 45 supported rotatably on a device main body. In this constitution, the flange 41 and shaft 45 are aligned with each other by the fitting part between the circular part of the hole 43a and the fitting part 46a to couple the carrier 2 concentrically with the shaft 45, and the pin 49 is fitted in the recessed part 43a to rotate the carrier 2 on the shaft 45. |
