摘要：
The image forming apparatus includes: a plurality of image forming units each having an image bearing member and a developing unit; and a transfer member provided to be able to contact the plurality of image bearing members. The toner used in at least one of the plurality of developing units contains a toner particle group with a particle size of 12.7 μm or more, a ratio of the toner particle group to the entire toner being 1.0% or less. Accordingly, incomplete transfer can be prevented.
