Abstract
PURPOSE:To obtain the images free from ground stains by letting developing bias be effectively acted. CONSTITUTION:The both end parts of the conductive substrate 1a of a photosensitive drum 1 are made smaller in diameter than the portion where a photosensitive layer 1b is formed and the both end parts of the core metal 5 of a developing roller 4 are made smaller in diameter than the portion covered with an elastic material layer 6. As a result of this, the toner supplied while being defined by a doctor blade 8 from a toner hopper 7 is conveyed by depositing only on the large-diameter elastic material layer 6 of the developing roller 4 and its contact with the conductive substrate 1a is obviated, thus the developing bias voltage being applied to the core metal 5 acts effectively and the toner deposition on the ground part is prevented.
