Image forming apparatus

An image forming apparatus having an image forming portion for forming an image on a sheet comprising:

• a housing configured to accommodate the image forming portion;
• a cassette configured to be inserted into and drawn out from the housing;
• and
• a conveying mechanism configured to at least partially define a conveying path for guiding the sheet to the image forming portion, wherein
• the conveying mechanism has a first conveying element including an upstream end on which a feeding assembly for feeding the sheet is formed, and a second conveying element confronting the first conveying element to form the conveying path in cooperation with the first conveying element, the second conveying element includes an upstream element extending along a sheet feed direction, and a pivotal downstream element connected to the upstream element,
• the housing includes a rail configured to guide the second conveying element from a first position where the second conveying element forms the conveying path along the first conveying element to a second position where the second conveying element is away from the first conveying element, the rail includes a first rail configured to guide the upstream element when the second conveying element is displaced from the first position to the second position, a second rail configured to guide the downstream element when the second conveying element is displaced from the first position to the second position, and a third rail configured to guide the cassette to be inserted and drawn out, the first rail and the second rail join together with the third rail, and
• the second conveying element located in the second position is configured to be guided by the third rail to move in a direction where the cassette is inserted and drawn out.
