  • Patent number: 8308253
    Abstract: An ink jet image forming apparatus includes a reset correction unit to restrict a heater driving time so as to prevent a heater from being damaged due to overheating when an error occurs in a system clock. The reset correction unit may determine that an error occurs in the system clock if a discharging voltage of at least one charging circuit, which performs a charging operation using the system clock, is decreased to a reference voltage. In this case, the reset correction unit can generate a reset signal having an initial state such that the heater is no longer driven.
