Abstract
A transfer voltage control method of an image forming apparatus includes supplying a first measurement voltage to a first transfer member and a second transfer member, measuring a variation in resistance of the first transfer member by supplying a second measurement voltage to the first transfer member during a first period of time, and measuring a variation in resistance of the second transfer member by supplying the second measurement voltage during a second period of time. Therefore, it is capable of measuring accurately a variation in resistance of a transfer unit, such that an optimum transfer voltage may be set. Accordingly, transfer quality of an image forming apparatus is improved.
