PROBLEM TO BE SOLVED: To stably obtain excellent electrifying performance and an excellent image by preventing the unevenness of the supply of electrification accelerating particles to an electrifying nip part in accordance with an image pattern and supplying the electrification accelerating particles to an electrification accelerating particle supporting member without unevenness substantially in an image forming device where an injection electrifying means using the electrification accelerating particles is set as the electrifying process means of an image carrier, the electrification accelerating particles are added to developer in a developing process means and the electrification accelerating particles are supplied to the electrifying nip part through the surface of the image carrier from the developing process means. SOLUTION: This device is provided with a means for deviating the supply distribution of the electrification accelerating particles (m) along in the longitudinal direction of the electrifying nip part (a). To put it concretely, the supply distribution of the particles (m) along in the longitudinal direction of the nip part (a) is deviated by providing a sequence for fluctuating an information writing position with respect to the image carrier 1, a sequence for fluctuating the position of the electrification accelerating particle supporting member 2 with respect to the image carrier 1 or the member for deviating the supply distribution of the particles (m) on the image carrier 1.
