A drawer is moveable between an inner position and an outer position through an opening when a cover is located at an opening position. A waste toner conveying tube is movable in a second direction between a first connection position and a first disconnection position when a drum cartridge is attached to a drawer and the drawer is at the inner position. When the cover moves from a closing position toward the opening position, the waste toner conveying tube moves from the first connection position toward the first disconnection position in conjunction with the movement of the cover. The drawer is movable from the inner position toward to the outer position when the drum cartridge is attached to the drawer, the drawer is at the inner position, and the waste toner conveying tube is at the first disconnection position.

An image forming apparatus includes a belt component, a first detachable unit that faces the belt component in an area where an outer surface of the belt component faces upward, a first housing component that houses the first detachable unit and is drawable from and loadable into the apparatus, a second detachable unit that faces the belt component in an area where the outer surface of the belt component faces downward, and a second housing component that houses the second detachable unit and is drawable from and loadable into the apparatus. With the first housing component being drawn from the apparatus, the first detachable unit is detachable from and attachable to the first housing component in a side-to-side direction. With the second housing component being drawn from the apparatus, the second detachable unit is detachable from and attachable to the second housing component in an upward direction.

A drawer is moveable between an inner position and an outer position through an opening when a cover is located at an opening position. A waste toner conveying tube is movable in a second direction between a first connection position and a first disconnection position when a drum cartridge is attached to a drawer and the drawer is at the inner position. When the cover moves from a closing position toward the opening position, the waste toner conveying tube moves from the first connection position toward the first disconnection position in conjunction with the movement of the cover. The drawer is movable from the inner position toward to the outer position when the drum cartridge is attached to the drawer, the drawer is at the inner position, and the waste toner conveying tube is at the first disconnection position.

An image forming apparatus including a main body casing, a cover, a drum cartridge, a developing cartridge, an intermediate transfer belt and a movable cam. The movable cam is movable among a first position when the cover is in the open position, a second position and a third position when the cover is in the closed position. In a case where the movable cam is in the first position, the photosensitive drum is in a first drum position spaced from the intermediate transfer belt, and the developing roller is in a first developing position spaced from the photosensitive drum. In a case where the movable cam is in the second position, the photosensitive drum is positioned toward the intermediate transfer belt from the first drum position. In a case where the cam is in the third position, the developing roller is positioned toward the photosensitive drum from the first developing position.

An image forming apparatus includes an apparatus main body to which a cartridge is detachably attached. The apparatus main body includes a frame having an opening portion through which the cartridge is attached to the apparatus main body; an opening and closing member supported by the frame rotatably between an open position in which the opening portion is exposed and a closed position in which the opening portion is covered with the opening and closing member and having a stacking surface on which a sheet is to be stacked; a discharging roller discharging the sheet in a discharging direction onto the stacking surface; and a regulating wall which is movably attached to the opening and closing member and extends from the stacking surface toward the discharging roller in a direction intersecting the discharging direction to regulate an upstream edge of the sheet in the discharging direction.

An image forming apparatus includes an image forming unit configured to form an image on a recording material, a printed circuit board including a voltage generation unit mounted thereon and configured to generate a voltage to be applied to the image forming unit, a conductive member provided on the printed circuit board, to which the voltage generated by the voltage generation unit is applied, an elastic member including an arm portion configured to be biased toward the conductive member, and configured to connect the conductive member and the image forming unit, and a holding unit configured to hold the arm portion of the elastic member at a position where the arm portion is not in contact with the conductive member.

A developing cartridge includes: a casing; a developing roller; a shaft extending in a first direction; a first inclined surface; a second inclined surface; an elastic member; and a first protrusion. The shaft is movable in the first direction relative to the casing and the developing roller, and is movable in the second direction together with the same. The first inclined surface is positioned at one end portion of the shaft, while the second inclined surface is positioned at another end portion of the shaft. The first and second inclined surfaces are inclined relative to the first direction. The first protrusion is movable in the first direction together with the second inclined surface. The shaft is movable from a first position to a second position when the second inclined surface receives a pressing force directed in a direction from the another end portion to the one end portion.

An image forming apparatus includes the following: an image forming portion; a first metal side plate and a second metal side plate provided opposite each other with respect to the image forming portion; an antenna for communicating with external equipment; a housing including a top cover that is provided above the first metal side plate and the second metal side plate in a vertical direction, and a side cover that is provided on an outer side opposite to an inner side where the image forming portion is provided with respect to the first metal side plate, wherein the image forming apparatus further includes a support member provided on the first metal side plate, the support member including a housing support portion that supports at least one of the top cover and the side cover, and an antenna support portion that supports the antenna.

An image forming device includes a device body; a conveyance table that is inserted into and pulled out of the device body and that forms a conveyance path for a sheet; a sheet mount tray; a paper feeder that feeds the sheet from the sheet mount tray to the conveyance path; and a movable support that movably supports the paper feeder on the conveyance table in a state where the conveyance table is pulled out of the device body. The paper feeder covers a predetermined part of the conveyance path in a state where the paper feeder disposed on the conveyance table is inserted into the device body, the sheet mount tray is disposed in the device body and separates from the paper feeder when the conveyance table is pulled out of the device body, and the paper feeder moves away from the predetermined part.
