There is provided an image forming apparatus including: an image supporting member having a first circumferential surface; an exposure section performing exposure of the first circumferential surface and thereby form latent images; a developer supporting member developing the latent images; a feeding member feeding a developer; and a control section controlling, while controlling exposure operation to allow the latent images to be formed side by side on the first circumferential surface, varying timing of a development voltage or both of the development voltage and a supply voltage to allow a portion P1 or both of the portion P1 and a portion P2 to be located within a gap between the latent images. The portion P1 is a portion, in the first circumferential surface, opposed to the developer supporting member. The portion P2 is a portion, in the first circumferential surface, opposed to a portion P3 of the developer supporting member.
