Abstract:
A process unit includes a photosensitive unit, a developer unit, a first urging member, and a second urging member. The first urging member urges the developer unit with a first urging force when the developer unit is in a contact position where a developing member contacts a photosensitive drum. The first urging member urges the developer unit with a second urging force greater than the first urging force when the developer unit is in a separated position where the developing member is separated from the photosensitive drum. The second urging member urges the developer unit with a third urging force smaller than the first urging force when the developer unit is in the contact position. The second urging member urges the developer unit with a fourth urging force smaller than the third urging force when the developer unit is moved from the separated position to the contact position.
