Abstract:
1. An image forming apparatus comprising: a rotating member supported rotatably; a rotatable coating brush that is wound spirally on a metal core in order to coat said rotating member with a lubricant; a supply unit for supplying the lubricant on said coating brush; a drive unit for driving said coating brush; and a controller for controlling said driving unit in such a way as to cause a rotating speed of said coating brush to fluctuate between an upper limit speed and a lower limit speed across a standard speed obtained by multiplying a rotating speed of said rotating member with a predetermined natural number; wherein said controller controls said driving unit in such a way as to cause a fluctuation cycle of the rotating speed of said coating brush and a cycle of said rotating member to be different in case when a mean rotating speed within one cycle of said coating brush matches with said standard speed while the rotating speed of said coating brush fluctuates.
