Abstract

A printer or copier has an intermediate carrier for applying toner to the recording medium. Used toner is scraped off the intermediate carrier and carried away by a conveyor helix. The conveyor helix is of a spring wire and a resistance element is provided extending between coils of the conveyor helix to intermittently catch and release the spring wire so as to cause wobbling of the conveyor helix and prevent sticking of the used toner.
