A charging member cleaning unit, that contacts a charging member that charges the surface of an image holding member provided in an image forming apparatus, and is used for cleaning the surface of that charging member, has an elastic layer, and has an amine content within the elastic layer of not more than approximately 60 ppm. The front lift assembly includes a front bellcrank that is rotatably coupled to the seat-mounting plate, a front pivot link that is rotatably coupled to the base plate, a carrier link that is pivotably coupled to the front pivot link and to the front bellcrank, and a front lift link that is rotatably coupled to the seat-mounting plate and is pivotably coupled to the front lift link. The data for such future load instructions can be prefetched from a distant cache or main memory such that when the load instruction is re-executed after the stall condition expires, its data will reside either in the L1 cache, or will be enroute to the processor, resulting in a reduced execution latency. If it does include that notation, the list is automatically modified to remove the notation. The invention also relates to assays for CCR3 receptor activity in which internalization andor kinase mediated phosphorylation of the receptor is reduced.
