摘要： A swinging gear is constructed to be swingable in accordance with the rotational direction of a main gear. A first gear train is arranged to drive a black developing unit by meshing with the swinging gear when the main gear is rotated in a first direction. A second gear train is arranged to drive developing units for colors such as yellow by meshing with the swinging gear when the main gear is rotated in a second direction reverse to the first direction.

摘要： A laser printer includes a contact/separation mechanism that linearly moves developing cartridges between contact positions where the developing cartridges contact corresponding photosensitive drums and separating positions where the developing cartridges separate from the photosensitive drums. The contact/separation mechanism includes a pair of contact/separation members and a synchronous moving mechanism. The contact/separation members are disposed one on one side of the developing cartridges and another on another side of the developing cartridges. The synchronous moving mechanism is for linearly moving the contact/separation members in synchronization with each other.

摘要： In an image-forming device including an image-carrying member, a developer-carrying member, and a casing having an inner space in which developer is accommodated and the developer-carrying member is supported, both a pushing force and a separating force are not applied to the casing so that the thickness of the casing does not need to be increased. The casing is formed with a pair of first protruding parts each having an end that protrudes outward along the axial direction of the developer-carrying member, and a pair of second protruding parts each having an end that protrudes farther outward than the corresponding end of the first protruding part. The first protruding parts serve as operating parts operated by the pressing member, and the second protruding parts serve as operating parts operated by the separating member.
