  • Patent number: 11320759
    Abstract: An image forming apparatus includes a rotatable photosensitive member. A charging member charges a surface of the photosensitive member. A developing roller carries developer. The developing roller supplies the developer in normal polarity to the surface of the photosensitive member. A regulating member regulates the developer on the developing roller. A common voltage applying unit applies charging voltage and regulating voltage. The regulating voltage is applied with the developing roller rotating such that a potential difference in a direction in which electrostatic force from the regulating member to the developing roller acts on the developer charged in the normal polarity, is formed between the regulating member and the developing roller, and in which the charging voltage to be applied in a non-image-forming period is controlled so as to be smaller in absolute value than in an image-forming period.
