Abstract:
An image forming device includes: element arrays each including light emitting elements arranged in main scanning direction, the arrays being arranged in sub scanning direction; a photoreceptor whose surface moves relative to the light emitting elements in the sub scanning direction; a controller outputting control voltage instructing light emission amount for each light emitting element; and drivers each supplying drive current to a corresponding light emitting element according to the control voltage, thus causing the light emitting element to emit light to expose the moving surface of the photoreceptor. Intervals L between the arrays satisfy (D/2)×(V/F)−((V/F)×0.1≤L≤(D/2)×(V/F)+((V/F)×0.1) where F expresses frequency of AC noise to be superimposed on the control voltage, V expresses system speed of the surface of the photoreceptor moving relative to the light emitting elements, and D is an odd number.

Claim (Index 1):
An image forming device comprising:\n a plurality of element arrays that each consist of a plurality of light emitting elements arranged in a main scanning direction, the element arrays being arranged in a sub scanning direction; a photoreceptor whose surface moves relative to the light emitting elements in the sub scanning direction; a controller that outputs a control voltage instructing a light emission amount for each of the light emitting elements; and a plurality of drivers that correspond one-to-one with the light emitting elements, and each supply a drive current to a corresponding one of the light emitting elements according to the control voltage, thus causing the light emitting element to emit light to expose the moving surface of the photoreceptor, wherein array intervals L between the element arrays in the sub scanning direction satisfy\n ( D/ 2)\u00d7( V/F )\u2212(( V/F )\u00d70.1)\u2264 L \u2264( D/ 2)\u00d7( V/F )+(( V/F )\u00d70.1) \u2003\u2003(1) \n where F expresses frequency of an AC noise to be superimposed on the control voltage, V expresses a system speed that is a moving speed of the surface of the photoreceptor relative to the light emitting elements, and D is an odd number.
