Abstract

A developing unit (13) in an image forming apparatus includes a bearing unit (27), a first biasing device (28), a shaft member (31), and a second biasing device (32). The bearing unit (27) rotatably supports the respective end portions of the developing roller (23) and the magnetic roller (24). The first biasing device (28) biases the bearing unit (27) in a direction to cause the developing roller (23) to move toward the image carrier (11). The shaft member (31) causes the bearing unit (27) to swing by moving in a front-back direction. The second biasing device (32) biases the shaft member (31) in a forward direction. A cover unit (15) of the image forming apparatus presses the shaft member (31) backward by pivoting from an open position to a closed position, and draws out the shaft member (31) in the forward direction by pivoting from the closed position to the open position.
