Sheet conveyance device with conveyance roller pair capable of conveying sheet

A sheet conveyance device comprising:

• a conveyance roller pair comprising a drive roller capable of being driven into rotation and a driven roller that follows a periphery of the rotating drive roller to rotate;
• a support portion that supports the driven roller;
• and
• a cover member configured to be openable and closable with respect to an interior of the sheet conveyance device and provided with the support portion,
• the driven roller comprising a rotary shaft and a roller body supported rotatably by the rotary shaft,
• the support portion comprising:
• a groove that is formed along a crosswise direction crossing an axial direction of the rotary shaft and receives the rotary shaft along the crosswise direction;
• a hook which is provided to project inwardly with respect to the groove and against which the rotary shaft is pressed;
• a biasing member that biases the rotary shaft toward the hook;
• and
• an elastically deformable lever including a base portion fixed to the cover member and a branched portion connected to an end of the base portion and extending toward the support portion, the branched portion having a distal end portion disposed between the biasing member and the rotary shaft,
• wherein the branched portion elastically deforms in accordance with a pressing force applied from the biasing member to the distal end portion, thereby causing the distal end portion to press the rotary shaft toward the hook.
