1. An image forming apparatus comprising:
an image former that forms an image on a sheet of paper;
a detector that detects a physical property of a sheet of paper;
a receiver that receives paper identification information designated by a user, the paper identification information being used in identification of a sheet of paper; and
a hardware processor that performs:
first judgement comprising judging whether there is a correspondence between the paper identification information received by the receiver and a detection result by the detector;
second judgement comprising judging whether there is a correspondence between a detection result by the detector with respect to a first sheet of paper conveyed and a detection result by the detector with respect to a second sheet of paper conveyed; and
operation control of the image former based on a first judgement result of the first judgement and a second judgement result of the second judgement,
wherein a judgment criterion in the first judgement is different from a judgment criterion in the second judgement.
