Abstract: An image processing apparatus includes an apparatus main body, a sheet feed cassette, a pull-in member, and a biasing member. The sheet feed cassette is provided to be insertable into the apparatus main body. The pull-in member pushes the sheet feed cassette from a pull-in start position to a pull-in complete position to pull in the sheet feed cassette to the apparatus main body. The biasing member biases the pull-in member in the insertion direction. The biasing force of the biasing member in the state where the pull-in member is at a first position closer to the pull-in complete position than the pull-in start position is larger than the biasing force of the biasing member in the state where the pull-in member is at a second position closer to the pull-in start position than the first position.
