ABSTRACT:
A feeding tray is detachably mounted on a base member and includes a bottom portion. The bottom portion has a first side that is configured to hold a recording sheet and a second side opposite the first side. An image forming unit forms an image on the recording sheet. A feeding roller is configured to rotatingly contact the recording sheet held in the feeding tray, thereby feeding the recording sheet toward the image forming unit in a conveying direction. A roller arm has one end that rotatably supports the feeding roller and another end opposite the one end. The roller arm is configured to swing about the another end, thereby generating a pressing force for pressing the feeding roller against the recording sheet. A supporting member is provided at the second side of the bottom portion and is configured to support the bottom portion against the pressing force.
