<p>A method for cleaning a photoreceptor of an image forming apparatus comprises the steps of actuating cleaning means of a cleaning system (8) and rotating the photoreceptor (1) before a usual image forming operation, after a predetermined time charging a particular area of the photosensitive drum (1), causing residual toner adhering to a sealing member (10d) of a developing unit to attract to the charged area, carrying the attracted residual toner with rotation of the photoreceptor to the cleaning means of the cleaning device (8), and removing the residual toner by the cleaning means. Accordingly, the present invention eliminates the possibility of mixing of colour of previously used toner into a toner image after replacement of a developing unit by another unit containing different colour of toner.</p> |
