An image formation device is disclosed that is able to detect data errors each time data are read from a memory in a cartridge and able to detect transmission error of the data. The image formation device includes a cartridge memory controller and a verification unit to verify reliability of data read from the memory of the cartridge. The cartridge reads both predetermined data and verification data stored in the memory unit, and sends the predetermined data and verification data to the image formation device; the verification unit compares the read-out verification data to verification data stored in a main body of the image formation device to verify reliability of the data read from the memory unit.
