Abstract: An image forming system includes an image forming unit that forms an image on a sheet based on printing data, a first processor that inspects the image formed by the image forming unit, and a second processor that determines whether a cause of an image defect is a fixing defect when the image defect is found by the first processor.

Abstract: A machine learning device learns an action of a driving source in a transport device continuously transporting at least two transported objects along a transport path, and includes: a hardware processor that: acquires position information of the at least two transported objects on the transport path on the basis of a result of detection by a sensor provided in the transport path; calculates a reward on the basis of the position information acquired, according to a predetermined rule; learns an action by calculating an action value in reinforcement learning on the basis of the position information acquired and the reward calculated; and generates and outputs control information that causes the driving source to perform an action determined on the basis of a learning result.
