摘要
An image forming apparatus includes a first light source, a second light source, an optical sensor, a storage, and a hardware processor that controls operation of the image forming apparatus, wherein the first wavelength and the second wavelength have a wavelength having a high correlation between the transmittance and the basis weight, compared with those at other wavelengths, and the hardware processor calculates a first transmittance from the amount of the first emission light and the amount of the first transmission light, calculates a second transmittance from the amount of the second emission light and the amount of the second transmission light, derives a first basis weight corresponding to the first transmittance, derives a second basis weight corresponding to the second transmittance, and derives a first average basis weight obtained by averaging the first basis weight and the second basis weight.
