Abstract: PROBLEM TO BE SOLVED: To provide an image forming apparatus configured to efficiently collect toner accumulated on a seal member arranged in an opening of a development apparatus which faces an image carrier.SOLUTION: An image forming apparatus includes an image carrier, a charging apparatus, an exposure apparatus, a development apparatus, a toner collection mechanism, and a control unit. The development apparatus includes a developing roller, a developer container, a seal member, and a supporting member for supporting the seal member. The toner collection mechanism collects toner scattering in the developer container. The control unit can execute a seal-member cleaning mode which forms an electrostatic latent image pattern including boundaries between an exposure part and a non-exposure part existing at a predetermined interval or less across the whole in a width direction of an image forming area of the image carrier when no image is formed, and rotates the image carrier so that the electrostatic latent image pattern passes through the seal member. The control unit calculates an amount of the toner collected by the toner collection mechanism every time when a predetermined number of sheets are printed, and changes an execution frequency of the seal-member cleaning mode in accordance with a calculation result.SELECTED DRAWING: Figure 2
