摘要： An image forming apparatus has an image bearing unit for bearing a toner image, a transfer device for transferring the toner image on the image bearing unit onto a sheet, fixing unit for fixing to the sheet toner image, and first and second sheet transport guides disposed along a transport path. A sheet transport speed in the fixing unit is set lower than a sheet transport speed in the transfer device. The first and second sheet transport guides are each disposed with a tilt with respect to a horizontal or vertical direction. A gap is provided to form a spacing sufficient to permit curves of the sheet to be formed between a downstream-side end portion of the first sheet transport guide and an upstream-side end portion of the second sheet transport guide.

摘要： A desired character mainly composed of standard width dots selected from a matrix of orthogonally disposed rows and columns is displayed on a screen during scanning of the screen in horizontal and vertical directions. The display is smoothed by a circuit responsive to data stored in a memory. The smoothing involves the selected addition or removal, to or from particular portions of the character, of a small dot having a width one-third of the standard dot width.
