Abstract
A cartridge includes: a second conveyance roller that forms a nip with a first conveyance roller; a storage portion that stores foreign matter; and a contact member that comes into contact with the second conveyance roller for restricting leakage of the foreign matter. An apparatus main body includes a biasing member that biases the second conveyance roller toward the first conveyance roller. The second conveyance roller is at a first position at which the nip is formed with the first conveyance roller by a biasing force of the biasing member when the cartridge is attached to the apparatus main body, and is at a second position when the cartridge is detached from the apparatus main body. The contact member is in contact with the second conveyance roller when the second conveyance roller is at the first position and when the second conveyance roller is at the second position.
