ABSTRACT:
An electrostatic recording apparatus and a management system thereof wherein the recording apparatus includes a photoconductor drum having a cap provided at an opening of the drum and a photoconductor sheet wound on a portion of the drum other than the opening, with the photoconductor drum being rotated. The cap is electrified and a capacitor is provided between the cap and a terminal and charged through the cap to maintain the cap in an electrified state. A potential of the terminal is equal to a ground potential or a potential approximating the ground potential. Further, a controller is provided for discharging the electrified electric charge of the cap in response to a discharge instruction. A managing system may be provided for judging the state of the electrostatic recording apparatus.
