摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus and a lubricant applying method for applying lubricant on a secondary transfer belt so as to suppress wear and peeling of a cleaning blade.SOLUTION: A temperature detecting unit 51 detects a temperature of paper at which the paper contacts a secondary transfer belt 41. A lubricant applying unit 47 increases an application amount of lubricant to paper as the temperature detected by the temperature detecting unit 51 increases. Accordingly, application of an unnecessarily excessive amount of lubricant on the secondary transfer belt 41 can be prevented, and thereby wear and peeling of a cleaning blade 48 can be suppressed.
