摘要： A method of controlling the charging operation of the contact charger of an electrophotographic apparatus including a photosensitive drum and a developing means for charging a toner with a negative voltage, the photosensitive drum and developing means being normally supplied with a negative voltage during printing, which includes the steps of: supplying a negative charging voltage of a specified level to the contact charger for a first interval defined as at least one initial rotation of the photosensitive drum in warm-up with the developing means not being supplied with a voltage, cutting off the negative charging voltage, and supplying a negative developing bias voltage which is lower than the surface voltage of the photosensitive drum to the developing means for a second interval defined as the interval before the stopping of the rotation of the photosensitive drum after the first period. Accordingly, negatively charged toner particles scattered by the developing means and abnormally attached to the photosensitive drum are moved from the photosensitive drum to the developing means owing to the electrical potential difference between the surface of the photosensitive drum and the developing means in the first interval, and positively charged ones of the toner particles are moved from the contact charger to the photosensitive drum and then to the developing means owing to the negative developing bias voltage in the second interval.
