ABSTRACT:
An image forming machine comprising a rotating drum having an electrostatic photoconductor on the peripheral surface thereof; a latent electrostatic image forming means for forming a latent electrostatic image on the electrostatic photoconductor; a developing means for developing the latent electrostatic image on the electrostatic photoconductor to a toner image; a transfer means for transferring the toner image on the electrostatic photoconductor onto a sheet member; a cleaning means for removing a residual toner remaining on the electrostatic photoconductor after transfer; and a fixing means for fixing the toner image, transferred onto the sheet member, onto the sheet member is provided. The rotating drum is rotationally driven by a first electric motor, and the fixing means is rotationally driven by a second electric motor. The cleaning means includes a rotary brush means in contact with the peripheral surface of the rotating drum. A selectively connecting means is disposed which can be selectively set in an operating state for drivingly connecting the rotary brush means to the second electric motor to transmit the rotation of the electric motor to the rotary brush means, and in a nonoperating state for cutting off the rotary brush means from the second electric motor. The selectively connecting means is set in the operating state only when the rotating drum is to be rotated.
