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.

Claim (Index 16):
An image forming device, comprising:\n a photosensitive element; a transfer element; a developer element, wherein:\n in a non-image-forming stage, the photosensitive element and the developer element are configured to have an electric field there-between, wherein in a first stage of the non-image-forming stage, a first potential difference is formed between the photosensitive element and the developer element; in a second stage of the non-image-forming stage, a second potential difference is formed between the photosensitive element and the developer element, and an absolute value of the first potential difference is less than an absolute value of the second potential difference, \n when the developer element uses 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, and \n when the developer element uses a positively charged developer, 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; and \n a voltage applying unit, electrically connected to the transfer element and configured to:\n continuously apply a first voltage to the transfer element in the first stage of the non-image-forming stage, and \n continuously apply a second voltage to the transfer element in the second stage of the non-image-forming stage, and \n an absolute value of the first voltage is greater than an absolute value of the second voltage, and a polarity of the first voltage and a polarity of the second voltage are opposite to a polarity of a potential on the surface of the photosensitive element.
