PROBLEM TO BE SOLVED: To provide an image forming device without any failure in electrifying or any failure in image and where merit of a cleanerless system is utilized by preventing attachment of residual developer of transfer to an electrifying means 2 and efficiently carrying out recovery of the residual developer of transfer by a developing means 4 in the image forming device of the cleanerless method where the residual developer (toner) of transfer on an image carrier 1 after a transferring process is eliminated, recovered and reused by the developing means 4. SOLUTION: In the device, the merit of the cleanerless system is obtained by controlling the triboelectricity of the residual developer of transfer, electrifying process of the triboelectricity of the residual developer of transfer to a normal polarity is carried by a developer electrified quantity control means 7 and the image carrier surface is electrified by the electrifying means 2 and simultaneously made to be an appropriate electrified quantity. |
