A development device includes a developer carrying member, developer collection conveyance path, and developer supply conveyance path. The developer carrying member carries a developer to develop an image on a latent image carrier. The developer collection conveyance path disposed obliquely above the developer carrying member conveys the developer in a first direction. The developer supply conveyance path disposed below the developer collection conveyance path conveys the developer in a second direction. The developer collection conveyance path and developer supply conveyance path have first and second openings and third and fourth openings respectively within a development region. The developer located downstream of the developer collection conveyance path is transferred to upstream of the developer supply conveyance path through the first and third openings. The developer located downstream of the developer supply conveyance path is transferred to upstream of the developer collection conveyance path through the fourth and second openings.
