Abstract

PURPOSE: To prevent the decrease in image density owing to moisture absorption of the developer on the exposed surface of a developer support means under a high- humidity environment by supplying the developer to a latent image holding means and developing the latent images then removing the remaining developer on the developer support means.
CONSTITUTION: Toner 4 is defined to the specified thickness by a doctor blade 3 at the A point on a sleeve 2 and develops the electrostatic images on a photosensitive or recording medium drum 1 at the proximate portion B by being restrained by adhesion force, electrostatic attraction force, magnetic force, etc. A sleeve 2 begins to rotate backward when it rotates by more than the angle AOC (C is the point of entry of the toner layer into a hopper vessel 5) allowing to the exposed AC and ends and stops backward rotation when the toner removed part of the sleeve 2 comes to cover the exposed part AC, whereby the toner layer is removed. Since this eliminates the thinly spread toner layer making direct contact with moist air, the degradation in the density of the mages may be suppressed.
