Image forming apparatus that selects appropriate power saving mode for each time slot

摘要

An image forming apparatus includes an operation panel, a printing device, a storage device, a job management unit, a power-saving mode setting unit, and an operation mode control unit. The power-saving mode setting unit that: (a) specifies the job log where the start time point of the job execution belongs to an identical time slot in a past for a predetermined time slot; and (b1) sets the power-saving mode for the predetermined time slot to the first power-saving mode when a proportion of the number of the executing jobs where the job types of the specified job log belong to the first job type group to the number of the executing jobs where the job types of the specified job log belong to the first job type group or the second job type group exceeds a predetermined threshold value.

1. An image forming apparatus, comprising:
an operation panel that accepts user operations; a printing device that executes a print job; a storage device that stores job classification data that indicates a job type belonging to a first job type group and a job type belonging to a second job type group; a job management unit that records the job type of an executing job and a start time point of the job execution as a job log; a power-saving mode setting unit that
(a) specifies the job log where the start time point of the job execution belongs to an identical time slot in a past for a predetermined time slot,(b1) sets a power-saving mode for the predetermined time slot to a first power-saving mode when a proportion of the number of the executing jobs where the job types of the specified job log belong to the first job type group to the number of the executing jobs where the job types of the specified job log belong to the first job type group or the second job type group exceeds a predetermined threshold value, and(b2) sets the power-saving mode for the predetermined time slot to a second power-saving mode when the proportion is equal to or less than the predetermined threshold value; and an operation mode control unit that causes an operation mode to be switched to the first power-saving mode or the second power-saving mode set by the power-saving mode setting unit when the operation mode is switched from a normal mode to the power-saving mode.
