Abstract:
There is provided a configuration in which a foreign object is less likely to drop onto a detection surface of a sensor when a protection member moves. The protection member is disposed above the sensor movably between a first position and a second position, and has a detection hole formed to expose a detection surface of the sensor at the first position. The protection member covers the detection surface in a part, in which the detection hole is not formed, at the second position. A protruding wall portion is provided at least at an upstream edge of the detection hole, with respect to a direction in which the protection member moves from the second position to the first position, so as to protrude upward from a top surface of the protection member.

Claim (Index 11):
An image forming apparatus comprising:\n an image forming unit configured to form a toner image; a rotational member onto which the toner image formed by the image forming unit is to be transferred; a first sensor disposed below the rotational member and facing a surface of the rotational member, the first sensor being capable of detecting the toner image on the rotational member; a second sensor disposed below the rotational member and facing the surface of the rotational member, the second sensor being capable of detecting the toner image on the rotational member; a shutter provided movably between each of the sensors and the rotational member, the shutter having a first detection hole, a second detection hole, and a cover portion, the first detection hole allowing detection of the toner image on the rotational member by exposing a first window for detection provided in the first sensor, the second detection hole allowing detection of the toner image on the rotational member by exposing a second window for detection provided in the second sensor, and the cover portion being configured to cover the first window and the second window, wherein the first window and the second window face the first detection hole and the second detection hole, respectively, when the shutter is at an opened position, and the first window and the second window face the cover portion when the shutter is at a closed position; a first protruding wall portion provided at the shutter, and provided to protrude upward at least at an upstream edge portion of the first detection hole, with respect to a direction in which the shutter moves from the closed position to the opened position; and a second protruding wall portion provided at the shutter, and provided to protrude upward at least at an upstream edge portion of the second detection hole, with respect to the direction in which the shutter moves from the closed position to the opened position.
