Abstract

An image forming apparatus which is capable of extending the life of relay contacts even when a noise filter circuit is disposed downstream of relays on paths over which commercial alternating-current power is supplied. First and second relays (801, 802) are disposed in respective ones of two supply paths that are different in polarity, over which power is supplied, and switch supply and shut off of the power. The noise filter circuit (811, 816) filters out noise on the supply paths. When supply of the alternating-current power to a power supplied device disposed downstream of the noise filter is started, one of the relays is switched into supply state first, and then the other one is switched into supply state so that the number of times each relay is switched into supply state first per predetermined number of times power is supplied can be substantially equal between the first and second relays.
