In a temperature dependent CPT-Violating (CPTV) axial time-like background (induced by the Kalb-Ramond tensor field of string theory) we discuss leptogenesis by solving the Boltzmann equation. The current work non-trivially modifies the framework of a previous phenomenological approach (where the author was involved) where the CPTV axial background was considered to be a constant. The constant background approximation is shown to capture the main phenomenological features of leptogenesis.
