An image forming apparatus includes the following. An image carrier forms an electrostatic latent image by exposure. A developing apparatus stores a developing agent including toner and which develops the image carrier. A collector collects in the developing apparatus the developing agent scattered from the developing apparatus. An input unit is used by a user to select a screen type relating to a fineness of a halftone image. An adjuster is able to change strength of an electric field between the collector and the image carrier. A hardware processor which controls the adjuster to change the strength of the electric field according to the selected screen type.

Image forming apparatus, image forming method, and storage medium

A developing device includes a hardware processor that performs control not to cause an image to be formed on an image bearing member by a first developer bearing member and to cause a first image to be formed on the image beating member by a second developer bearing member, in which the hardware processor corrects developing conditions of the plural developer bearing members based on a developability detection result of the first image formed by the second developer bearing member.
