摘要： PROBLEM TO BE SOLVED: To provide an inexpensive optical sensor capable of detecting the density of color toner even when the density of the color toner is high and accurately detecting the adhesion position of the color toner, and to provide an image forming apparatus provided with the optical sensor. SOLUTION: A reflection-type photosensor 70 as the optical sensor includes: a light-emitting part 77 emitting light toward the surface 29a of a conveying belt 29 to which the color toner is made to adhere; and a light-receiving part 78 receiving the light regularly reflected by the surface 29a. The light-emitting part 77 is provided with a light-emitting diode 71 emitting ultraviolet light, and the light-receiving part 78 is provided with a photodiode 72 outputting a signal corresponding to the quantity of received ultraviolet light. The ultraviolet light has low reflectance in the color toner, thereby: making smaller the quantity of the light reflected by the color toner; and preventing the light regularly reflected by the color toner from being received by the light-receiving part 78.

摘要： PROBLEM TO BE SOLVED: To provide an optical sensor and an image formation apparatus that permit surface mounting of light emitting means and/or light receiving means in a prescribed attitude or prescribed attitudes relative to a substrate.SOLUTION: Supporting projections 34e are provided, one in a position opposing the front side end part (lens side) of the trunk of a light emitting element 31 of a printed circuit board 34 and the other in a position opposing the vicinity of the rear side end part (the side reverse to the lens side) of the trunk. This arrangement causes the front and rear sides of the trunk of the element to be supported by the supporting projections 34e and prevents the element from oscillating with a terminal as the fulcrum. As a result, even if the element is touched before solder filling the gap between a connecting part 34d of the printed circuit board 34 and the terminal hardens, the element is prevented from inclining forward or backward (in the optical axis direction).

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.
