Abstract

An image forming method includes when an image forming device is in a non-image-forming stage, applying voltages to a surface of a photosensitive element and a surface of a developer element of the image forming device to form an electric field. Applying the voltages includes: forming a first potential difference between the photosensitive element and the developer element in a first stage, and forming a second potential difference between the photosensitive element and the developer element in a second stage. When a developer used by the developer element is a negatively charged developer, a direction of the first potential difference and a direction of the second potential difference are in a direction from the developer element to the photosensitive element. When positively charged, the direction of the first potential difference and the direction of the second potential difference are in a direction from the photosensitive element to the developer element.
