Abstract

Disclosed is an image forming apparatus that enables to transversely move a sheet separator without a dedicated drive source and with a simplified construction to thereby reduce production cost of the apparatus. The image forming apparatus includes a thrust driving mechanism for reciprocating the sheet separator in an axial direction of a heater roller. The mechanism includes a worm gear which is rotated by a driving force of a drive source for rotating the heater roller, a helical gear which is meshed with the worm gear, and an eccentric cam which is mounted coaxially with an axis of rotation of the helical gear. A guide member for supporting the sheet separator is reciprocated in the axial direction of the heater roller in accordance with rotation of the eccentric cam.
