Abstract
An image forming apparatus includes an optical sensor configured to measure reflected light from a test image on the image carrier. The optical sensor includes a printed circuit board, with a light-emitting element provided on a first surface of the printed circuit board, and with the light-emitting element being configured to irradiate the test image on the image carrier with light. The optical sensor also includes a light-receiving element provided on the first surface of the printed circuit board, with the light-receiving element being configured to receive the reflected light from the test image on the image carrier. A connector is provided on a second surface of the printed circuit board opposite to the first surface of the printed circuit board, with a cable for controlling the optical sensor being connected to the connector. A support member is configured to support the optical sensor so that the first surface of the printed circuit board faces a surface of the image carrier, and a controller is configured to control the image forming unit based on a result of the reflected light from the test image measured by the optical sensor. A direction in which the cable is inserted into the connector is orthogonal to the second surface of the printed circuit board.
