Abstract
An image forming apparatus includes a causal member identifying section, and a judgement section. The causal member identifying section identifies the causal member as a cause of the periodic unevenness based on the period of the periodic unevenness which has been detected by the periodic unevenness detector. The judgement section judges whether or not the periodic unevenness is transient based on the information of the causal member identified by the causal member identifying section, the information of at least one of a resting time in which the image forming apparatus has been left inoperative, an operating time of the causal member, and the image forming condition for image formation, and the information of a temperature and a humidity inside the image forming apparatus.
