Claim:
1. An image forming apparatus comprising: a developing portion configured to carry a magnetic brush including toner and a carrier and bring the magnetic brush into contact with an effective outer circumferential surface of an outer circumferential surface of a rotating photosensitive member on which effective outer circumferential surface an electrostatic latent image can be formed, thereby to develop the electrostatic latent image into a toner image; a previous charge removal light-emitting portion configured to apply charge removal light to a charge removal target region of the effective outer circumferential surface of the photosensitive member which charge removal target region includes a part of a magnetic brush contact region with which the magnetic brush is brought into contact and a region between the magnetic brush contact region and a transfer position of the toner image; and a charge removal light control portion configured to change a light amount of the previous charge removal light-emitting portion in accordance with a density of the toner image on the charge removal target region, wherein the charge removal light control portion makes the light amount of the previous charge removal light-emitting portion smaller when the density of the toner image on the charge removal target region is high than when the density of the toner image is low.
