Image forming apparatus and method of forming an image

A method of forming an image in an image forming apparatus, the image forming apparatus including:

• an image forming section including a light exposure section configured to expose an image bearing member to light to form an electrostatic latent image, the image forming section being configured to form a toner image on the image bearing member, and to form an image on a recording sheet by transferring the toner image onto the recording sheet, the method comprising:
• a first step of estimating a density lowering position on the basis of image data of an image formed by the image forming section, the density lowering position being a position where decrease in image density relative to a predetermined image density is caused in the image;
• and
• a second step of controlling the light exposure section to increase a light exposure amount at the density lowering position estimated by the estimation section on the image bearing member to an amount greater than a predetermined light exposure amount.
