Image forming apparatus and non-transitory recording medium storing a computer readable control program

Abstract

The image forming apparatus includes an image bearing member, a developing section, and a controller that functions as a sign detector, a charge amount measurement section, and a charge amount adjuster. On the image bearing member, an electrostatic latent image is formed based on image data. The developing section contains a developer, and develops the electrostatic latent image formed on the image bearing member with the developer to form a toner image. The sign detector detects a sign that the charge amount of the developer contained in the developing section changes. The charge amount measurement section measures the charge amount of the developer in accordance with the detection result by the sign detector. The charge amount adjuster adjusts the charge amount of the developer according to the measurement result by the charge amount measurement section.
