Image forming apparatus

摘要

According to an embodiment, an image forming apparatus includes a job queue that registers jobs and a controller that executes the jobs according to an order in which the jobs are registered in the job queue. Further, when a plurality of jobs that differ in a control temperature of a heat source are registered in the job queue, the controller sorts the jobs in the job queue so that a required time until execution of all the jobs is completed becomes shortest.

主权项

1. An image forming apparatus comprising:
an image forming unit that forms an image on a sheet; a heat source that heats the sheet at a control temperature according to a job type; a storage unit including a job queue that registers jobs in a received order; and a controller that, when a plurality of jobs that differ in the control temperature are registered in the job queue:
groups the lobs registered in the job queue into job groups that differ in the control temperature,determines whether a speed of temperature increase of the heat source is larger than a speed of temperature decrease of the heat source with respect to the corresponding control temperatures of the job groups,changes an execution order of the job groups in the job queue so that a required time for execution of all the job groups is shorter than any other execution order based on the determination of whether the speed of temperature increase is larger than a speed of temperature decrease, andexecutes the jobs registered in the job queue according to the changed order.
