装置。 In an image forming apparatus that applies a developer to a latent image formed in an image area on the circumferential surface of a cylindrical image carrier to make it visible, a latent image corresponding to a non-image area on the circumferential surface of the image carrier in the development area A covering sheet is provided to cover the end portion, and the covering sheet is formed into a substantially L-shape in which a portion to be aligned in the circumferential direction of the peripheral surface of the carrier and a portion to be aligned in the width direction intersect at an angle greater than 90°. and when the covering sheet is attached to the image carrier, it is deformed in a direction in which the intersection angle is narrowed so that at least the edge on the image area side is brought into close contact with the surface of the image carrier. Device.
