Abstract
A recording material detecting apparatus includes a light guiding unit that allows first and second light to enter a surface of a recording material, respectively, in two directions which are not parallel; an imaging device that images a first light irradiated area and a second light irradiated area, on the surface of the recording material; and an output device that outputs information on a surface condition of the recording material based on an output of the imaging device. When viewed in a direction along the center optical axes of first and second light sources which are of the same type, the first and second light sources are arranged such that the respective reference lines of the rotational phases around the center optical axes are rotated in opposite directions by approximately the same angles from a line perpendicular to the direction where the first and second light sources are arrayed.
