Image forming apparatus that executes fax job concurrently with print job while reducing delay in fax job processing, job execution method, and storage medium

Abstract

An image forming apparatus includes a processing circuit, a memory, a data reception circuit, a bus, and a transmission amount control circuit. The processing circuit concurrently executes a plurality of jobs including a fax job and a print job. The memory is used for a work area of the processing circuit. The data reception circuit stores the image data received via the communication network in the memory. The bus connects a plurality of modules including the processing circuit and the data reception circuit to the memory. The transmission amount control circuit reduces an amount of data transmission from the data reception circuit to the memory via the bus when the processing circuit executes the print job concurrently with the fax job, compared with a case where the print job is executed concurrently with any job other than the fax job.
