Abstract

It is conventional practice in a xerographic process to tone the photo-conductor's latent image by mechanical engagement with a developer mix comprised of carrier and toner. For example, the photoconductor's latent image is passed through a magnetic brush developer.

Xerographic Process

It is conventional practice in a xerographic process to tone the photo- conductor's latent image by mechanical engagement with a developer mix comprised of carrier and toner. For example, the photoconductor's latent image is passed through a magnetic brush developer.

After toning, the photoconductor moves to a transfer station whereat a portion of its toned image is transferred to a copy sheet. Thereafter, it is conventional to clean the photoconductor of residual toner, etc. For example, a cleaning brush mechanically scrubs the photoconductor as the brush rotates counter to photoconductor movement.

Mechanical engagement of the developer mix and the brush to the photoconductor may produce excessive photoconductor wear, and perhaps undesirable coating of the photoconductor.

To prevent these results, it is desirable to turn on the developer and cleaning brush only when an image is to be toned and thereafter cleaned. In particular, it has been found desirable to never allow the cleaning brush to sweep the photoconductor when the developer has not just previously subjected that section of the photoconductor to the developer mix.
