An image forming apparatus includes an image forming part, a canceling processing part, a first switching processing part and a second switching processing part. The canceling processing part is performable an image canceling operation where a toner image formed on an intermediate transferring member is removed from the intermediate transferring member without transferred to a sheet. The first switching processing part is capable of switching a printing mode in the image forming part between a plurality of printing modes having different printing conditions in the image forming part, based on an image data under waiting for printing and a predetermined first switching condition. The second switching processing part is capable of switching the printing mode based on the image data under waiting for printing and a predetermined second switching condition when the image canceling operation is performed.
