PROBLEM TO BE SOLVED: To prevent secret leakage even when data stored in an image forming apparatus are referred to. SOLUTION: When printing ciphered printing data transmitted to the image forming apparatus, a deciphering key to be used for deciphering them is requested to a host device (S308 and S309), the deciphering processing of the printing data is performed by using the key (S310) and a printing processing is carried out (S311).
