  • Patent number: 11415928
    Abstract: An image forming apparatus includes a feeding device to feed residual toner, discharged from an image forming portion, toward a first collecting container and a second collecting container selectively. The feeding device includes an aggregate feeding passage to aggregate the residual toner discharged from a first or second image forming portion and feed the residual toner in an aggregate feeding direction traversing an up down direction. A vertical conveyance passage is provided along the up down direction and connected to the aggregate feeding passage, and a lateral feeding passage is connected to the vertical conveyance passage and capable of feeding the residual toner in a lateral feeding direction traversing the up-down direction. The feeding device feeds the residual toner in the lateral feeding passage toward the first collecting container and the second collecting container.
