Claims18
An image forming apparatus comprising:
- a tray configured to accommodate a plurality of sheets which are conveyed out of the tray for printing;
- a pickup roller configured to feed the sheets in the tray for printing;
- a pressing member movable between a first position at which the pressing member presses the plurality of sheets against the tray and a second position at which the pressing member does not press the plurality of sheets against the tray, the pressing member including a portion that is positioned more downstream in a sheet conveying direction than at least one portion of the pickup roller;
- a drive mechanism configured to cause the pressing member to be moved between the first and second positions;
- and
- a control unit configured to control the drive mechanism to move the pressing member into the first position, while a sheet is not supplied for printing from the tray and into the second position while the sheet is supplied for printing from the tray.
An image forming apparatus comprising:
- a tray configured to accommodate a plurality of sheets which are conveyed out of the tray for printing, the tray having a sheet support on which the sheets are stacked;
- a pickup roller configured to feed the sheets in the tray for printing;
- a plate member above the sheets, the plate member including a portion that is positioned more downstream in a sheet conveying direction than at least one portion of the pickup roller;
- a drive mechanism configured to move the sheet support to press the sheets against a lower surface of the plate member;
- and
- a control unit configured to control the drive mechanism to move the sheet support in a direction towards the plate member, while a sheet is not supplied for printing from the tray.
