Image forming apparatus
An image forming apparatus includes an apparatus main body, a fixing device, a conveying guide and a branching guide. In the apparatus main body, a conveying path and an inversion path are formed. The conveying guide guides the sheet along the conveying path closer to a downstream side than the fixing device. The branching guide guides the sheet toward an ejecting part along the conveying path closer to the downstream side than the fixing device and guides the sheet toward the inversion path along the conveying path closer to the downstream side than the fixing device. The conveying guide is detachably attached to one of the apparatus main body and the fixing device so as to cover a part of the fixing device from a downstream side in a conveying direction of the sheet. The branching guide is detachably attached to the conveying guide.
