    摘要： An image forming apparatus includes an image bearer, a developing unit configured to develop a latent image formed on the image bearer with a toner to form a toner image, and a transfer member including a contact area that comes in contact with the image bearer. The toner image is primary transferred from the image bearer to the transfer member. A speed difference between the image bearer and the transfer member at the contact area is 0.1% or greater but 0.8% or less. The toner has an average circularity of 0.971 or greater but 0.986 or less and a shape factor SF-2 of 110 or greater but 119 or less. The speed difference is represented by the following formula: Speed difference [%]={(V1−V2)/V2}×100  [Speed difference] where V1 is a linear speed of the image bearer, and V2 is a linear speed of the transfer member.
