<P>PROBLEM TO BE SOLVED: To provide an optical sensor unit that reduces noise caused by crosstalk included in an output value of a detection target and obtains the resulting output value, and suppresses an increase in costs for the unit, as well as an image forming apparatus. <P>SOLUTION: An opposite part 131, which is placed opposite to a light entrance and exit surface 38 of a sensor unit 30 of a shutter member 130, is made smooth and inclined relative to the light entrance and exit surface 38 to be an inclined surface 131a. The inclined surface 131a is irradiated with light, and then an output voltage of a first light-receiving element 32 and an output voltage of a second light-receiving element 33 are detected, and thereby a crosstalk voltage of the first light-receiving element 32 and a crosstalk voltage of the second light-receiving element 33 are detected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
