An image forming apparatus includes a cover and a supporting unit. The supporting unit includes a holding member, a supporting member, a first biasing unit, and a positioning unit. The holding member holds the transferring member. The supporting member movably supports the holding member, so that the transferring member can move toward or away from a specific member arranged in the main body. The first biasing unit biases the transferring member toward the specific member. When the cover is in a closed state, the transferring member is pressed against the specific member. The positioning unit performs positioning of the supporting member with respect to the main body.
