Abstract
Provided are image forming apparatuses, non-transitory recording media each storing a computer-readable program for obtaining paper information, and paper-information obtaining methods. An image forming apparatus includes at least one reflection-type optical sensor that measures a sheet in a sheet path, and at least one backing configured to change optical density of a backing face which is to be placed under a sheet in the sheet path for a measurement of the sheet with each of the at least one reflection-type optical sensor. A hardware processor in a system including the image forming apparatus, causes the at least one reflection-type optical sensor to take measurements of a sheet in the sheet path by using different optical densities of the backing face, and calculates paper weight, which is weight of paper per unit area, of the sheet on the basis of the result of the measurements.
