Abstract: An image forming apparatus includes a rotatable photosensitive member including a photosensitive layer and a light transmitting surface layer provided outside the photosensitive layer; an exposing unit configured to expose the surface of the photosensitive member to a laser beam which deflects in a main scan direction substantially perpendicular to a moving direction of the surface of the photosensitive member, so that a latent image formed on the surface of the photosensitive member in the main scan direction; and a controller configured to control a pulse width of an image signal for switching, on the basis of image data, between projection and non-projection of the beam from the exposing unit. The controller controls the pulse width such that it is smaller than when the thickness of the surface layer is larger. An image forming apparatus includes a rotatable photosensitive member including a photosensitive layer and a light transmitting surface layer provided outside the photosensitive layer; an exposing unit configured to expose the surface of the photosensitive member to a laser beam ...more ...less

Abstract: A developer container includes a container, provided with an opening and configured to accommodate a developer; a sealing member configured to cover the opening; and an unsealing member configured to unseal the opening by moving the sealing member. The sealing member opposes the container at a central opposing portion positioned in a central side and at an end opposing portion positioned at an end side with respect to a longitudinal direction of the unsealing member. The sealing member and the container are bonded to each other at bonding portion which is at least a part of the central opposing portion. The bonding force at the bonding portion of the central opposing portion is larger than a bonding force between the sealing member and the container at the end opposing portion. A developer container includes a container, provided with an opening and configured to accommodate a developer; a sealing member configured to cover the opening; and an unsealing member configured to unseal the opening by moving the sealing member.
