The development device includes a magnet roller, which includes a shaft having magnets arrayed circumferentially, and a cover member, which include a bearing part engaged with the guide part as the shaft is inserted thereinto. The shaft and the bearing part include an engaged part and an engaging part restricting a circumferential position of the magnet and including contact faces provided along an action direction of force from the guide part to the bearing part when the bearing part is engaged with the guide part and the development device approaches the image carrier. A clearance is provided between an outer circumferential face of the shaft and an inner circumferential face of the bearing part at an upstream side in the action direction from the contact faces.
