Abstract
An image forming apparatus in an embodiment includes an image carrying body, a transfer body, a first mechanism, a sensor, and a second mechanism. The image carrying body carries an image of a developer. The image of the developer is transferred onto the transfer body from the image carrying body. The first mechanism separates the transfer body from the image carrying body. The sensor detects a state of the surface of the transfer body. The second mechanism separates the sensor from the transfer body in association with the first mechanism.
Claims20
An image forming apparatus, comprising:
- an image carrying body configured to carry an image of a developer;
- a transfer body onto which the image of the developer is transferred from the image carrying body;
- a first mechanism configured to separate the transfer body from the image carrying body;
- a sensor configured to detect a state of a surface of the transfer body;
- and
- a second mechanism configured to separate the sensor from the transfer body, wherein
- the transfer body is configured to move in a first direction,
- the sensor is disposed so as to be separated from the transfer body in a second direction orthogonal to the first direction, and
- the sensor includes a plurality of local sensors disposed to be separated in a third direction orthogonal to the first direction and the second direction.
