PROBLEM TO BE SOLVED: To prevent, regardless of a change in the linear velocity of a photoreceptor, degradation of the ability to prevent toner scatter, in an image forming device equipped with an exposure device, using a laser beam or an LED for example, and a two-component developing device. SOLUTION: The linear velocity of the paddle-like stirring member 43 of the developing device 4 or that of a developing roll 41 situated furthest downstream in a developing area is independently changed with a change in the linear velocity of the photoreceptor 1 matching the switch of recording-line density. This always stabilizes the action of a suction pump which causes air to flow from a space 10 into the developing device 4 forcibly, preventing scatter of insufficiently-electrified toner floating downstream in the developing area. |
