    摘要: A low density area is caused at a trailing edge of an image formed on a photosensitive drum. This low density area is less likely to be caused when the density of the image is higher and the humidity is lower. To prevent generation of such low density area, if a color misregistration detection toner pattern having a high density is formed, in a low humidity environment, an excessively large amount of toner is consumed unnecessarily. In response, the density of the color misregistration detection toner pattern is adjusted based on the humidity.

    摘要: The present invention provides a sheet conveying apparatus, and an image reading apparatus and an image forming apparatus having such a sheet conveying apparatus, in which skew correction of a sheet can be effected with high accuracy. A sheet convey means is provided at an upstream side of a skew correction means for correcting skew-feed of a sheet, and the sheet convey means is shifted by a shift means in a direction substantially perpendicular to the sheet conveying direction. A control means drives the shift means to shift the sheet convey means pinching the sheet to be skew-corrected by the skew correction means by a distance corresponding to a sheet skew amount on the basis of sheet skew amount information from a sheet skew amount detection means for detecting a skew amount of the sheet, thereby shifting the sheet in a skew correction direction.
