Abstract

Provided is an image forming apparatus capable of preventing or suppressing occurrence of density unevenness even when a shearing force is applied between an image face on paper and a fixing belt. The image forming apparatus includes an image former, a fixer, and a controller. The image former forms a toner image constituted by a plurality of dots each containing a toner on paper. The fixer includes a fixing member moving at a first velocity and a pressure member forming a fixing nip portion with the fixing member and moving at a second velocity, and fixes the toner image on the paper at the fixing nip portion. When the first velocity and the second velocity at the fixing nip portion are different, the controller determines a toner amount to be attached to paper so as to make a toner amount distribution different in each of the dots before fixing.
