When the moisture of a carrier is adsorbed for a measure to make {HEAD ~ an environmental difference} less, that is, for preventing {TAIL ~ the environmental variations} of a carrier itself, the measure can be achieved with the use of a material of which the chargeability is weakly made to be negative
