Abstract
An image forming apparatus () includes a discharge section (), a paper receiving tray (), a first detecting section (), a lever (), a second detecting section () and a decision section (). The first detecting section () is disposed in the discharge section (), and detects a paper jam. The second detecting section () detects a swinging state of the lever () from a first position at which the lever () is not in the process of receiving an action of the paper sheet to a second position. The decision section () judges an occurrence factor in a paper jam to be a user-induced factor when the second detecting section () detects a state in which the lever is at the first position in a state where the first detecting section () detects the paper jam. Also, the decision section () judges the occurrence factor in the paper jam to be an image forming apparatus-induced factor when the second detecting section () detects a state in which the lever is swung over the first position in the state where the first detecting section detects the paper jam.
