Image forming system which continues image formation of confidential document under condition that presence of executor is confirmed

摘要

An image forming apparatus includes: a biometric information reading section which acquires biometric information of a printing executor; a biometric information sending section which sends the biometric information acquired by the biometric information reading section to an authentication server; a confidential printing section which starts image formation of a confidential document when the printing executor has been authenticated by the authentication server; storage which stores therein the biometric information acquired by the biometric information reading section as comparison biometric information; and an authentication section which performs presence confirmation of the printing executor by acquiring biometric information through the biometric information reading section and comparing the biometric information to the comparison biometric information during the image formation of the confidential document. The confidential printing section continues the image formation of the confidential document under a condition that the presence of the printing executor is confirmed by the authentication section.
