Sheet conveying device and image forming apparatus incorporating same

A sheet conveying device comprising:

• an opening-and-closing member having a lower end configured to be supported by an apparatus body, the opening-and-closing member configured to be rotatable to open and close a sheet conveyance path;
• a pressing member included in the opening-and-closing member, the pressing member configured to press a pressed member of the apparatus body;
• a hook configured to engage with an engaging member of the apparatus body, and to hold the opening-and-closing member at a closing position at which the opening-and-closing member closes the sheet conveyance path;
• a biasing member configured to bias the hook in a direction to maintain engagement of the hook with the engaging member;
• a first adjuster configured to adjust at least one of a pressing force of the pressing member or a protrusion amount of the pressing member with respect to a surrounding member of the pressing member;
• and
• a second adjuster, wherein
• the first adjuster and the second adjuster are on a first end and second end, respectively, in an axial direction of the pressing member, and the first adjuster and the second adjuster are configured to be movable in a specified range with respect to the opening-and-closing member, and
• the first adjuster and the second adjuster are further configured to move to switch at least one of the pressing force or the protrusion amount in a stepwise manner.

• and
• a second adjuster, wherein
• the first adjuster is further configured to adjust at least one of the pressing force or the protrusion amount of the pressing member so that a tangential force at a contact portion between the hook and the engaging member is greater than a force of stopping sliding of the hook on an outer circumferential surface of the engaging member, the tangential force acting on the contact portion in response to the hook riding over the engaging member and engaging with the engaging member.
