摘要： An electrophotographic image forming apparatus has a photosensitive drum; a charging device for charging a surface of the photosensitive drum; an LED array for projecting a light beam on the surface of the photosensitive drum, thereby forming irradiated spots constituting an electrostatic latent image. The irradiated spots are formed on intersections of a grid which is composed of a plurality of first lines extending in a main-scanning direction and arranged at equal first intervals and a plurality of second lines extending in a sub-scanning direction and arranged at equal second intervals. The apparatus also has a developing device for attaching a toner particle extending to each of the irradiated spots, a transfer device for transferring the toner particle to a transfer material, and a fixing device for fixing the toner particle on the transfer material. A diameter of the toner particle is determined in such a way that a diameter of a fixed toner particle is equal to approximately a length of a diagonal line of the grid. Further, the diameter of the toner particle in the developing device is in a range of 0.7 times to 1.0 times as long as the first interval and/or the second interval.

摘要： A sensor detects the leading edge of the print medium. A position counter counts a time length required for the print medium to advance from where the print medium is detected by the sensor to the photosensitive drum. The position counter also counts a time length for the print medium to advance past the photosensitive drum. The distance of the toner image from the leading edge of the print medium is determined on the basis of the image data of print data. A row counter counts the number of dots in a direction in which the print medium is transported and a column counter counts the number of dots in a direction perpendicular to the direction the print medium is transported. The distance between the first line of an image data and the line in which a first dot to be printed in the image data is determined on the basis of the contents of the column counter and the row counter. The controller switches the transferring device from the constant current control mode to the constant voltage control mode immediately before the first line is printed on the print medium, thereby allowing transferring of the toner image in accordance with the distance of the toner image from the leading edge of the print medium.

摘要： An image forming apparatus for collecting, through a developing device, and reusing remaining toner remained on a photosensitive drum, as an image carrier, for forming an electrostatic latent image, without being transferred to a transfer material, includes a toner uniforming member disposed between locations for a charging process and for an exposing process, for making the toner remained on the photosensitive drum during a transferring process adhere slightly and uniformly to the photosensitive drum. The toner uniforming member eliminates the remaining toner remained on the photosensitive drum temporarily, and is applied with a necessary voltage for making the remaining toner eliminated temporarily adhere to the surface of the photosensitive drum again.

The developing roller rotates in the direction opposite to that of the image carrier and a peripheral velocity of the developing roller exceeds 1.2 times that of the image carrier.
