Abstract (en)

A first control member (22) is disposed in a drum shaft (21) away from a photoconductive drum (12), and a second control member (23) is disposed in a roller shaft (25) away from a transfer roller (16). The first and second control members (22, 23) abut on each other at their circumferential surfaces. This helps reduce an amount of displacement resulting from an impact caused by insertion of a recording paper sheet (19) in between the photoconductive drum (12) and the transfer roller (16), and thereby reduce vibrations in the photoconductive drum (12). Consequently, a toner image formed on the photoconductive drum (12) and an unfixed toner image transferred onto the recording paper sheet (19) are not affected by vibrations, so that a high-quality image is obtained that is free from blurriness or irregularities.
