An image processing apparatus is provided. The image processing apparatus includes: a transport unit configured to transport a sheet; an access unit configured to access a storage medium attached to the sheet transported by the transport unit; a first determination unit configured to determine a length of an access time required for the access unit to complete access from a time when the access is started; and a change unit configured to change control to the transport unit such that a passing time during which a sheet attached with a storage medium transported by the transport unit passes an access range of the access unit increases when the first determination unit determines that the access time is a first length, as compared with the passing time when the first determination unit determines that the access time is a second length shorter than the first length.
