An information processing apparatus which is used for an exposure system has a generation unit which generates format information required to inform a user with respect to a control parameter used in the exposure system, based on the control parameter, and an output unit which outputs the parameter information and the format information out of the apparatus. The at least one resilient member is electrically connected to the at least one ground element and the at least one protrusion is generally positioned between the at least one resilient member and the at least one arm assembly. The shackle extends from the first end portion of the lock body. below the fluorothermoplastic melting temperature for a time sufficient to resurface of the outer surface of the fuser member. Embodiments also include a double-layer mesh cover with an air gap existing between the two mesh layers.
