The nuclear charge distribution function is derived from statistical theory as a function of the most probable charge transfer variable defined by the most stable charges of fission fragments. The fine structures observed in the charge distribution width, skewness and excess can be described by the present formula in terms of charge shift due to pairing effects, as well as in asymmetric terms of nuclear mass. According to an investigation on the fine structure by a semi-empirical method, some remarks are given for the saddle and scission states.
