PURPOSE:To reduce abrasion and noise between an intermediate transferring drum in which the transferring positional deviation of a transferring drum is reduced and a photosensitive drum on the transferring mechanism of a printing device having the cylindrical photosensitive drum having a surface where a toner image is formed and a cylindrical transferring drum transferring the toner image from the photosensitive drum. CONSTITUTION:This mechanism is provided with a driving means 3 to drive the rotary shaft 6 of the transferring drum 2 in a vertical direction, a co-ordinate detecting means 4 to detect the positional co-ordinate of the center of the rotary shaft 6, and a driving controlling means 5 which finds a difference between a circular orbit and the positional co-ordinate of the rotary shaft 6 detected by the co-ordinate detecting means 4 in a rotation angle detected by an angle detecting means 7 detecting the rotation angle from a specified reference position to the circular orbit and which commands to correct the difference by feeding back the difference to the driving means 3, when the rotary shaft 6 of the drum 2 draws the specified circular orbit by the driving means 3 in order to correct the eccentricity of the transferring drum 2. |
