Abstract
An image forming apparatus is configured such that a second photosensitive drum is disposed between a first toner container and a first developing container in a first direction, a part of a first pipe is disposed to pass a region outside a light path of a laser beam radiated from a laser scanner to the second photosensitive drum in a second direction, and at least a part of a wall is a region between the part of the first pipe and the light path in the second direction and is disposed in a region overlapping with the light path when viewed in a direction of a rotational axis of the second photosensitive drum.
Claims9
An image forming apparatus comprising:
- a laser scanner;
- a first photosensitive drum configured to be irradiated with a laser beam by the laser scanner to form an electrostatic latent image on a surface of the first photosensitive drum, the first photosensitive drum being configured to be rotatable;
- a second photosensitive drum configured to be irradiated with a laser beam by the laser scanner to form an electrostatic latent image on a surface of the second photosensitive drum, the second photosensitive drum being arranged in line with the first photosensitive drum in a first direction intersecting with a gravitational direction;
- a first developing unit including a first developing roller configured to supply a first toner to the first photosensitive drum to develop a first toner image, and a first developing container configured to store the first toner to be carried by the first developing roller;
- a second developing unit including a second developing roller configured to supply a second toner to the second photosensitive drum to develop a second toner image, and a second developing container configured to store the second toner to be carried by the second developing roller;
- a first toner container configured to store the first toner to be supplied to the first developing container;
- a second toner container configured to store the second toner to be supplied to the second developing container, the second toner container being arranged in line with the first toner container in a second direction intersecting with the gravitational direction and the first direction;
- a first pipe configured to allow the first toner to be supplied from the first toner container to the first developing container to pass through, the first pipe being bendable and flexible;
- a second pipe configured to allow the second toner to be supplied from the second toner container to the second developing container to pass through, the second pipe being bendable and flexible;
- and
- a wall configured to regulate a position of the first pipe,
- wherein the second photosensitive drum is disposed between the first toner container and the first developing container in the first direction,
- wherein, in the second direction, a part of the first pipe is disposed to pass a region outside a light path of the laser beam radiated from the laser scanner to the second photosensitive drum, and
- wherein at least a part of the wall is a region between the part of the first pipe and the light path in the second direction, and is disposed in a region overlapping with the light path when viewed in a direction of a rotational axis of the second photosensitive drum.
