Abstract
An image forming apparatus includes a transfer belt that conveys a transfer material, and a photosensitive body that catches the transfer material between the photosensitive body and the transfer belt and that transfers a toner image to the transfer material. The transfer belt is driven in conjunction with the opening action of the front cover, and the photosensitive body is separated from the transfer belt in conjunction with the opening action of the front cover.
Claims12
An image forming apparatus, comprising:
- a transfer belt that conveys a transfer material;
- a photosensitive body that catches the transfer material between the photosensitive body and the transfer belt and transfers a toner image to the transfer material, wherein the transfer belt is driven in conjunction with an opening action of a front cover, and the photosensitive body is separated from the transfer belt in conjunction with the opening action of the front cover;
- a first gear and a second gear;
- and
- a first rotation roller that suspends the transfer belt in a tensioned state and a second rotation roller,
- wherein the first gear is attached to the first rotation roller, the second gear is coupled to the first gear,
- wherein the opening action of the front cover causes the rotation of the second gear which rotates the first gear, the rotation of the first gear then rotates the first rotation roller, and the rotation of the first rotation roller then moves the transfer belt, and
- wherein at least one of the first gear and the second gear is a one-way gear.
An image forming apparatus, comprising:
- a transfer belt that conveys a transfer material;
- a photosensitive body that catches the transfer material between the photosensitive body and the transfer belt and transfers a toner image to the transfer material, wherein the transfer belt is driven in conjunction with an opening action of a front cover, and the photosensitive body is separated from the transfer belt in conjunction with the opening action of the front cover;
- and
- a fixing unit that fixes the toner image transferred to the transfer material on the transfer material, wherein the fixing unit moves integrally with the front cover,
- wherein the fixing unit includes:
- a rotatable heating member,
- a pressurizing member that rotates while making contact with and pressing the heating member, and
- a biasing member that makes the heating member and the pressurizing member be in contact with each other with pressure by biasing one of the heating member and the pressurizing member,
- wherein the biasing member biases one of the heating member and the pressurizing member only when the front cover is in a closed state.
An image forming apparatus, comprising:
- a transfer belt that conveys a transfer material;
- a photosensitive body that catches the transfer material between the photosensitive body and the transfer belt and transfers a toner image to the transfer material, wherein the transfer belt is driven in conjunction with an opening action of a front cover, and the photosensitive body is separated from the transfer belt in conjunction with the opening action of the front cover;
- and
- a fixing unit that fixes the toner image transferred to the transfer material on the transfer material, wherein the fixing unit moves integrally with the front cover, and
- wherein the front cover is rotatably connected around at least one fulcrum and is connected with the fixing unit through a linear electrically connecting unit that passes around the fulcrum.
