Abstract:
1. An image forming apparatus comprising: an electrostatic-latent-image carrying body which has a latent-image forming surface formed in parallel with a predetermined main scanning direction and configured such that an electrostatic latent image in the form of an electric potential distribution is formed thereon, and which is configured such that the latent-image forming surface can move along a sub-scanning direction orthogonal to the main scanning direction; and a developer supply apparatus disposed to face the electrostatic-latent-image carrying body, and configured to supply a developer in the form of fine particles onto the latent-image forming surface in a state in which the developer is charged, wherein the developer supply apparatus includes: wherein the insulating substrate is supported by the substrate support member such that the transport electrodes face a developer transport path formed along the inner wall surface of the developer containing casing, and margin areas of the insulating substrate, which are regions of end portions of the insulating substrate with respect to the sub-scanning direction in which regions the transport electrodes are not formed, are separated from the developer transport path.
