Image forming apparatus having imaging units using toner with different particle sizes

摘要

An image forming apparatus includes four first imaging units that use standard toners for colors of yellow, magenta, cyan, and black, respectively. The image forming apparatus further includes a second imaging unit that uses a toner having a particle size smaller than a smallest one of particle sizes of the four standard toners. The image forming apparatus also includes a transfer unit that transfers first images formed by the respective first imaging units and a second image formed by the second imaging unit to a recording medium such that the first images are provided on the recording medium and the second image is provided on the first images.
