In a job allocation control apparatus, whether or not a job has security setting is discriminated, if it is decided that the job has the security setting, this job is set to a scheduling target to a clean device, and if it is decided that the job does not have the security setting, this job is set to a scheduling target to a non-clean device. When a process of the job having the security setting as a scheduling target to the clean device cannot be executed, the job having the security setting is set to the scheduling target to the non-clean device. Whether or not the non-clean device satisfies a predetermined condition is discriminated. If the predetermined condition is satisfied, the job having the security setting is transmitted to the non-clean device.
