Abstract: Provided is an image formation apparatus having a paper tray which is removably provided to an apparatus main body, in which sheets are loaded on a lifting plate, and from which the sheets on the lifting plate are fed by a paper feeding device, and the apparatus includes a holder that holds the lifting plate at a position higher than a lowest position when the paper tray is pulled out of the apparatus main body and the sheets are loaded on the lifting plate, wherein the holding by the holder is canceled to make the lifting plate go down to the lowest position before an operation of inserting the paper tray into the apparatus main body is completed.

Abstract: A sheet feed cassette having: a main body to be set in a body of an image forming apparatus; a first press-up member configured to support print media stacked thereon; a first elastic member configured to apply an elastic force to make the first press-up member press up the print media; a second press-up member; a second elastic member configured to apply an elastic force to make the second press-up member press up the first press-up member or the print media; an adjusting mechanism configured to adjust the force of the second press-up member to press up the first press-up member or the print media in accordance with a size of the print media; and a regulatory mechanism configured to prevent the second press-up member from pressing up the first press-up member or the print media when the main body is detached from the body of the image forming apparatus.

Abstract: An image forming apparatus acquires front and back images to be formed on paper and divides the front and back images of paper into a first image formed a part of the front image, a second image formed of the remaining part of the front image and a part of the back image, and a third image formed of the remaining part of the back image. The image forming apparatus forms the first and second images on the paper folded at the first position, and forms the third image on the paper folded at the second position. The image forming apparatus forms the first to third images such that the part of the front image and the remaining part of the front image constitute the front image and the part of the back image and the remaining part of the back image constitute the back image when the paper is unfolded.

Abstract: An image forming apparatus includes a sheet cassette, a sheet feed roller, and a separating blade. An image forming section and a sheet conveying path for conveying a sheet to the image forming section are placed in a position within the width of a cassette body defined in a sheet feeding direction and above the cassette. The tip of the separating blade is placed in a portion of stacked sheets accommodated in the cassette between a front end portion and a rear end portion of the cassette. The sheet feed roller is placed in a position between the front end portion and the rear end portion of the cassette and apart from the tip of the separating blade toward the rear end portion.

Abstract: An image forming apparatus having a door on a side surface of a body of the apparatus. Three pivot points for supporting the door to be capable of pivoting horizontally are disposed in the rear side of the apparatus body, in an upper section, in a middle section and in a lower section, respectively. The upper pivot point and the lower pivot point are adjustable with reference to the middle pivot point.
