An image forming apparatus includes: an image bearer bearing a toner image; a transferer transferring the toner image from the image bearer onto a recording material and including a transfer member forming a transfer nip between itself and the image bearer; and a fixer fixing portion for fixing on the recording material the transferred toner image and including a fixing sleeve, a heater contacting an inner surface of the fixing sleeve, and a pressing roller for forming a fixing nip between itself and the heater through the fixing sleeve. At least one of the fixing sleeve and the pressing roller is grounded through a first series circuit consisting of a rectifying element and a first resistance element and is grounded through a second series circuit, which is connected to the first series circuit in parallel, consisting of a capacitive element and a second resistance element.
