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 1):
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 sensor disposed below the rotational member and facing a surface of the rotational member, the sensor being capable of detecting the toner image on the rotational member; a shutter provided, between the sensor and the rotational member, movably in a widthwise direction perpendicular to a movement direction of the rotational member, and configured to cover at least a part of the sensor, the shutter having a detection hole and a cover portion, the detection hole allowing detection of the toner image on the rotational member by exposing a window for detection of the sensor, the cover portion being configured to cover the window, wherein the window and the detection hole face each other when the shutter is at an opened position, and the window and the cover portion face each other when the shutter is at a closed position; and a protruding wall portion provided at the shutter, and provided to protrude upward at least at an upstream edge portion of the detection hole, with respect to a direction in which the shutter moves from the closed position to the opened position.
