PURPOSE: To prevent the surface of a photosensitive body from being damaged by a simple means, by charging electrostatically a paper powder removing means placed in the vicinity of the photosensitive body, to the same polarity as the toner electrostatic charge polarity, and attracting and removing a paper powder on the surface of the photosensitive body by a Coulomb force generated between said means and the paper powder.

CONSTITUTION: A paper powder 3 attracted electrostatically to a photosensitive body 1 approaches a paper powder removing device 2 together with a residual toner 4, following a rotation of the photosensitive body 1. The residual toner is charged electrostatically for instance, to (-), therefore, repels a (-) charge of a paper powder removing means 21 and remains adhering to the photosensitive body 1. The paper powder 3 is attracted by the paper powder removing means 21 because a Coulomb force generated against this paper powder removing means 21 is stronger than a Coulomb force against the photosensitive body 1, and removed selectively from the surface of the photosensitive body 1. The paper powder 3 adhering onto the paper powder removing means 21 is scraped down by a blade 22 and discharged to the outside of a system. The residual toner 4 is destaticized, and thereafter, removed from the surface of the photosensitive body 1, and recycled to a developing mechanism 13. In this way, it is prevented that the surface of the photosensitive body is damaged.
