DEVELOPING VOLTAGE CONTROL METHOD OF IMAGE FORMING APPARATUS

摘要

PURPOSE: A developing voltage control method of an image forming apparatus is provided to optimize printing quality by automatically controlling a developing voltage responding to a temperature change of an inside of an image forming device. CONSTITUTION: When a printing instruction is received(S1), a transcription resistance of a transcription roller is measured(S2). A stored developing voltage of a developing roller responding to the measured transcription resistance of a transcription roller is detected(S3). A temperature of an inside of an image forming device is measured(S4). The measured temperature of an inside of an image forming device is compared with a reference temperature(S5). When the measured temperature is greater than the reference temperature, the detected developing voltage is provided to a developing roller(S7). When the measured temperature is smaller than the reference temperature, the developing voltage is increased by a set variable value and is provided to the developing roller(S6).
