A medium conveying device includes an alignment member, a skew conveying member, and a removal member. The alignment member faces one end of a medium and aligns the medium while contacting with the medium when the medium is conveyed in a first direction. The skew conveying member conveys the medium in a second direction crossing to the first direction so that the one end comes in contact with the alignment member and that includes a drive member and a driven member opposed to the drive member and driven by the drive member. The removal member has a tip end coming in contact with a face of the drive member to remove a deposit on the face. The removal member is placed along a rotation direction of the drive member so that the tip end faces downstream of the rotational direction.

A recording-material transport apparatus includes a retracting member that moves at a speed lower than a transport speed of a recording material transported from an upstream side in a transport direction, to a downstream side in the transport direction along a transport path for the recording material, and that retracts from the transport path after a leading end of the recording material contacts with the retracting member, a first transport member that transports the recording material from the upstream side in the transport direction toward the retracting member, and a second transport member that further transports the recording material in contact with the retracting member to the downstream side. After the leading end of the recording material contacts with the retracting member, without being paused, transport of the recording material with the first transport member is continued to deliver the recording material to the second transport member.

A sheet transport device includes an abutment member that moves downstream in a sheet transport direction and against which a leading end of a sheet that has been transported from upstream in the sheet transport direction abuts; and a transport unit that transports the sheet whose leading end has abutted against the abutment member further downstream. The abutment member moves at least to the transport unit in a state in which the leading end of the sheet abuts against the abutment member, and the abutment member is separated from the leading end of the sheet after the transport unit has started to transport the sheet.

A medium conveying device includes a first guide member, a second guide member, a conveying member, and a support member. The first guide member guides one face of a medium to be conveyed and opposed to the one face when the medium is conveyed. The second guide member guides the other face of the medium and is opposed to the other face when the medium is conveyed, the second guide member being movable between a close position and an open position. The conveying member is provided in a conveying passage formed by the first guide member and the second guide member being at the close position in order to convey the medium in the conveying passage. The support member keeps the second guide member at the open position and is provided at a position outer than the second guide member in a direction that the medium is conveyed. When the second guide member is at the open position, the medium in the conveying passage is removable from the conveying passage.

An image forming apparatus is capable of detecting the presence or absence of sheets before a bottom plate moves up during a so-called initial operation, such as an operation for setting a sheet loading tray in the apparatus, and preventing the bottom plate from running wildly during, for example, an upward movement thereof. The apparatus includes an image forming unit for forming an image on a sheet transferred thereto, a sheet loading tray having a bottom plate which is loaded with sheets to be transferred to the image forming unit, and which is adapted to be vertically moved, a sheet nudging member for feeding the sheets from an upper side of the sheets stacked on the bottom plate toward the image forming unit, a first sensor provided above the sheet loading tray and adapted to detect the presence or absence of the sheets, a second sensor provided on the bottom plate of the sheet loading tray and adapted to detect the presence or absence of the sheets, and a control unit for controlling the vertical movements of the bottom plate of the sheet loading tray.
