A sheet feeding apparatus includes: a transfer medium loading tray that is movable vertically; a hardware processor configured to control vertical movement of the transfer medium loading tray; an overload detector configured to detect transfer media of a maximum loading amount prescribed for each type of the transfer media; and an intermediate tray position detector configured to detect the transfer medium loading tray being at an intermediate tray position prescribed for each type of the transfer media, wherein the hardware processor is configured to control the vertical movement of the transfer medium loading tray in accordance with a type of the transfer media and on a basis of a vertical position of the transfer medium loading tray, results of detection by the overload detector, and results of detection by the intermediate tray position detector.

A sheet feeding apparatus includes a supporting portion and a feeding unit. The supporting portion supports a sheet and is capable of being drawn out from and being attached to an apparatus body. The feeding unit is provided in the apparatus body and includes a feeding portion, a conveyance portion, a separation unit, and a guide member. The feeding portion feeds the sheet supported by the supporting portion. The conveyance portion conveys the sheet. The separation unit forms a separation nip with the conveyance portion and is detachable from the feeding unit. The guide member includes a guide surface and a lower surface. The guide surface guides the sheet to the separation nip. The lower surface is provided below the guide surface and includes an exposing portion exposing at least a part of the separation unit.

An image forming apparatus includes a selection unit configured to select a sheet type, an image processing unit configured to perform image processing on image data, based on a correction condition that corresponds to the selected sheet type, a conveyance unit configured to convey a sheet, and an image forming unit configured to form an image on the sheet, based on the image data, wherein the image processing unit performs the image processing on the image data, based on a first correction condition that corresponds to a sheet to be conveyed by the conveyance unit in a first direction, and wherein the image processing unit performs the image processing on the image data, based on a second correction condition that corresponds to a sheet to be conveyed by the conveyance unit in a second direction, the second direction being different from the first direction.

According to an embodiment, an image processing apparatus includes a detector, a heater, and a controller. The detector detects an image formed on a sheet. The heater applies a predetermined heat amount onto the sheet to carry out erasing processing on the sheet. The controller controls, based on a detection result of the detector, the number of times the erasing processing is to be carried out on the sheet and a heat amount to be applied onto the sheet in the erasing processing.

A sheet feed cassette includes a bottom portion, a first cursor, a second cursor, and a fixing rack. The second cursor includes a regulating member, a lock member, and a biasing member. The regulating member abuts on the rear end edge of the sheet to regulate a position of the sheet in the mounting direction. The lock member includes a shaft portion extending in a direction intersecting with the mounting direction and an engaging protrusion located below the shaft portion. The biasing member is located and compressed between the regulating member and the lock member above the shaft portion. The gear teeth of the fixing rack and the engaging protrusion of the lock member engage so as to lock a position of the second cursor in the mounting direction. The regulating member and the lock member are separated above the shaft portion in the locked state.

A sheet feed device includes: a stacking tray on which sheets are stacked in such a manner as to be capable of being lifted and lowered; and a position restricting member configured to come into contact with a sheet end portion to restrict a position of the sheets. The position restricting member is provided to an opening/closing member capable of being opened and closed. When the opening/closing member is closed, the position restricting member restricts a position of the sheet end portion in an opening/closing direction of the opening/closing member.

An image forming apparatus includes a conveyer roller exposed to an attachment space and a drive force transmission mechanism for transmitting a drive force from a drive source. The drive force transmission mechanism includes a plate driving gear exposed to the attachment space, a transmission gear train transmitting a drive force to the conveyer roller and to the plate driving gear, and a switching mechanism. The switching mechanism includes a driven gear transmitting the drive force to the transmission gear train, a pendulum gear revolvable between a coupled position in which the pendulum gear is engaged with the driven gear and an uncoupled position in which the pendulum gear is separated from the driven gear, and a transmission switch movable between a first position for holding the pendulum gear in the uncoupled position and a second position for allowing the pendulum gear to revolve between the coupled and uncoupled positions.

A method of easily determining which sheet is conveyed from which sheet storage unit in a case where a test chart is printed on sheets conveyed from a plurality of sheet storage units is provided. The control method includes performing control to convey a first sheet from a first sheet storage unit, printing on the first sheet, based on that the first sheet is a sheet conveyed from the first sheet storage unit, a print test image and first identification information that identifies the first sheet storage unit, performing control to convey a second sheet from a second sheet storage unit, and printing on the second sheet, based on that the second sheet is a sheet conveyed, a print test image and second identification information that identifies the second sheet storage unit.

This image forming apparatus includes: a plurality of sheet accommodating portions each including a sheet placement portion on which a sheet is placed; a lifting/lowering portion configured to lift and lower the sheet placement portion; an image forming portion configured to form an image on the sheet supplied from each sheet accommodating portion; and an engine control portion configured to control the image forming portion on the basis of inputted print data. The engine control portion causes the lifting/lowering portion to lift the sheet placement portion to a predetermined sheet feed possible position in response to reception of the type of the sheet, and after the image formation by the image forming portion is finished, the engine control portion causes the lifting/lowering portion to lower the sheet placement portion to a predetermined original position.

A sheet feeding apparatus includes: a transfer medium loading tray that is movable vertically; a hardware processor configured to control vertical movement of the transfer medium loading tray; an overload detector configured to detect transfer media of a maximum loading amount prescribed for each type of the transfer media; and an intermediate tray position detector configured to detect the transfer medium loading tray being at an intermediate tray position prescribed for each type of the transfer media, wherein the hardware processor is configured to control the vertical movement of the transfer medium loading tray in accordance with a type of the transfer media and on a basis of a vertical position of the transfer medium loading tray, results of detection by the overload detector, and results of detection by the intermediate tray position detector.
