An image forming apparatus includes an image carrying member unit having an image carrying member, a developing unit insertable into and drawable out of the image forming apparatus, and a transfer member. The image carrying member unit is movable between a first position where the image carrying member makes contact with the transfer member and a second position where they are apart. The image carrying member unit or the image forming apparatus has a biasing member that biases the image carrying member unit toward the second position. With the developing unit fitted to the image forming apparatus, the image carrying member unit is at the first position against a biasing force of the biasing member. With the developing unit drawn out of the image forming apparatus, the image carrying member unit is at the second position due to the biasing force of the biasing member.
