A method that enables an image forming device of efficient memory sharing between processes and a kernel in a simple multiple-process-configuration. The image forming device has a real address space including a DMA buffer area and a shared memory area, a virtual address spaces, and job page assurance (JPA) programs. The virtual address spaces of the executing processes are mapped onto the real address space. The DMA buffer area can be accessed by the kernel. The shared memory area stores a job list and a job management list. The processes in the virtual address spaces include identical JPA libraries. Each of the JPA libraries requests the kernel to allocate of one page non-compressed data memory size for the job in the DMA buffer area, and upon completion of the job output, requests the kernel to release the allocated area and alters the contents in the job management list accordingly.
