IMAGE FORMING APPARATUS HAVING INTEGRATED SENSING UNIT

摘要

An image forming apparatus is provided. The apparatus includes an integrated sensing unit, which includes an optical sensor including a light emitting part and a light receiving part to receive light emitted from the light emitting part, and an actuator which selectively blocks light to be received by the light receiving part. The actuator includes a shaft member that is elastically supported in one rotation direction, a light blocking member that is mounted on the shaft member and is selectively positioned between the light emitting part and the light receiving part, and a first contact member and a second contact member distanced from each other on the shaft member.
