Image forming apparatus capable of changing partitions of storage unit, and control method and storage medium therefor

摘要

An image forming apparatus capable of changing partitions of a storage unit without using another storage unit stored with a system for partition change. At startup of the image forming apparatus, a file system is developed on a DRAM from a flash memory and executed by a CPU of the image forming apparatus. When determining that partition change is to be performed, a partition change module that operates on the CPU performs the partition change in a state where the flash memory is not mounted. Subsequently, an operating system placed on the flash memory is started up.

1. An image forming apparatus comprising:
a printing unit configured to perform printing; a volatile storage unit; a nonvolatile storage unit configured to be stored with a file system and divided into a plurality of partitions, wherein the plurality of partitions include at least an image development partition in which an image to be printed by the printing unit is developed; a development unit configured to develop the file system on the volatile storage unit; and a change unit configured to change at least one to-be-changed partition of the plurality of partitions of the nonvolatile storage unit by using the file system developed by the development unit, wherein the change unit saves data of the to-be-changed partition into the image development partition, and changes the to-be-changed partition after the data has been saved into the image development partition, wherein a data save process is not performed for the image development partition, when the to-be-changed partition is the image development partition, before the change of image development partition, and wherein the image development partition is larger in size than the other partitions of the plurality of partitions.
