Abstract: A surgical instrument includes a rod unit extending in a first direction along a tibia of a human body, an attachment located at a first end of the rod unit that is attachable to an ankle joint, and a fastener located at a second end of the rod unit that is fasten-able to a proximal end of the tibia. The fastener has a through-hole extending in a second direction that crosses the first direction, and a pin that is arranged in the through-hole and that has a tip which is received in the tibia. The through-hole has an opening larger than a profile of the pin to allow the fastener to move about a portion of contact between the through-hole and the pin when the pin is received in the tibia.

Abstract: An electrophotographic photosensitive member includes a photosensitive layer of a single layer. The photosensitive layer contains a charge generating material, a hole transport material, an electron transport material, and a binder resin. An optical response time is 0.05 milliseconds or longer and 0.85 milliseconds or shorter.

The pulse light has an intensity that allows the surface potential of the photosensitive layer to decay to +200 V from +800 V after 400 milliseconds elapse from the irradiation of the surface of the photosensitive layer charged to +800 V with the pulse light. The photosensitive layer has a Martens hardness at 50° C. of at least 160 N/mm2.
