摘要：
A method of measuring density includes detecting movement of a moving member in a light path of light emitted from a light emitting member, measuring an output of a light receiving member for a case where the moving member is moved in the light path, as a first output, detecting that the moving member is not in the light path, measuring an output of the light receiving member for a case where the moving member is not in the light path, as a second output, and calculating density based on the first output and the second output.
