Patent ID: 8836963

Claim:
An image processing apparatus comprising: a fixing device that has a fast heating mode in which temperature is relatively rapidly increased and a heat storage mode in which heat is stored in advance in a heat storage member for relatively high productivity, as a fixing mode in which a fixing member that heats a recording sheet for fixing is heated in advance, in a process of performing an image forming process with respect to the recording sheet; and a selection section that selects any one of a case where execution of a job indicating an image forming process of a predetermined batch throughput is instructed, and when the fixing device returns to a normal power state from a power saving state, the fixing mode in which the image forming process is early completed is selected on the basis of a total throughput of the job to perform the image forming process, and a case where during the total throughput of the job is not determined or in a case where the job corresponds to a plurality of sets, the fast heating mode is selected as an initial operation for at least the first set to perform the image forming process.
