Abstract
A method of supplying a developing unit with toner and an image forming apparatus using the method are provided. The method may include supplying toner to a developing unit separate from a toner bottle in an image forming apparatus. The method includes: detecting a remaining amount of toner in the developing unit during printing; comparing the remaining amount of toner with a first reference value; if the remaining amount of toner is greater than the first reference value, continuing printing; and if the remaining amount of toner is not greater than the first reference value, determining whether to supply toner based on a preset mode. Deterioration of printing quality in a toner supply mode may be markedly reduced according to a user's settings.
