Abstract

See full text

An image forming apparatus includes a developing member, a first detection processing portion, and an acquisition processing portion. The developing member conveys developer to a facing portion between the developing member and the image-carrying member. The first detection processing portion detects a first development current for each of a plurality of specific voltages with different DC voltage values applied to the developing member, the first development current flowing, in response to application of the specific voltages, through the facing portion including the developer and a specific exposed area, formed by the light emitting portion, on the image-carrying member. The acquisition processing portion acquires a potential value of the specific exposed area based on the DC voltage values of the specific voltages and current values of the first development current, detected by the first detection processing portion, corresponding to the respective specific voltages.
