Abstract
A developing unit in an image forming apparatus includes a bearing unit, a first biasing device, a shaft member, and a second biasing device. The bearing unit rotatably supports the respective end portions of the developing roller and the magnetic roller. The first biasing device biases the bearing unit in a direction to cause the developing roller to move toward the image carrier. The shaft member causes the bearing unit to swing by moving in a front-back direction. The second biasing device biases the shaft member in a forward direction. A cover unit of the image forming apparatus presses the shaft member backward by pivoting from an open position to a closed position, and draws out the shaft member in the forward direction by pivoting from the closed position to the open position.
