摘要： Improvements in a device for removing the electrostatic charge on a photoconductor in an image forming apparatus. The electrostatic charge-removing device has a plurality of light-emitting diodes (LEDs) incorporated in a case. The LEDs emit diffuse light to the photoconductor to remove the electrostatic charge. The LEDs are regularly spaced from each other in a orthogonal direction to a movement direction of the photoconductor in such a way that the successive diffuse light radiations emitted from the neighboring LEDs overlap with each other. The brightness is considerably higher in the locations where the diffuse light radiations overlap with each other than in the other locations. Light-blocking members are mounted upstream of their respective light radiations as viewed in the movement direction of the photoconductor, for uniforming the brightness of light in the orthogonal direction to the movement direction of the photoconductor. This evens out the image erasure line.

摘要： A sheet cassette is provided with a sheet accommodating portion capable of accommodating a plurality of sizes of sheets, a side-fence member movable in conformity with the size of sheets to be accommodated into the sheet accommodating portion so as to be brought into contact with the sheets at a specified side, and a position defining portion for defining an arranged position of the side-fence member in correspondence with the size of the sheets. The position defining portion includes at least a first size display section having indices set based on a first index criterion, and a second size display section having indices set based on a second index criterion different from the first index criterion. The side-fence member includes a first pointer for indicating the indices of the first size display section and a second pointer for indicating the indices of the second size display section.
