A drum unit includes: a frame; a first photosensitive drum; a second photosensitive drum; a charger; and a storage medium. The frame includes: a first frame plate; a second frame plate spaced apart from the first frame plate in a first direction; a third frame plate connecting one end of the first frame plate to one end of the second frame plate; and a fourth frame plate connecting another end of the first frame plate to another end of the second frame plate. The first photosensitive drum and the second photosensitive drum are rotatably supported by the frame. The second photosensitive drum is spaced apart from the first photosensitive drum and positioned closer to the third frame plate than the first photosensitive drum to the third frame plate in a second direction. The storage medium has an electrical contact surface positioned at an outer surface of the third frame plate.

An image forming apparatus includes a casing, a cover unit, and a liquid channel. The cover unit is disposed above an image forming unit. The cover unit includes a first member, a second member, and a neighboring portion positioned between the first member and the second member. The liquid channel is configured to guide liquid and includes a first channel and a second channel. The first channel is disposed between the neighboring portion and the image forming unit. The first channel includes a recess part and a liquid outlet. The recess part is disposed below the neighboring portion and extending toward the frame in an extending direction. The liquid outlet is positioned at an end portion of the recess part in the extending direction. The second channel is disposed at the frame. The second channel is configured to allow liquid to pass through the frame in the extending direction.

A sheet feeder is provided that includes a housing, a feed tray having a loading surface, and a swingable opening cover including a sliding contact portion, extending in a direction perpendicular to a width direction of a sheet. The sliding contact portion is configured to slide in contact with a feed tray in a swing motion of the feed tray from a first position where the loading surface is directed downward above the housing to a second position where the loading surface is directed upward at an upstream side relative to the housing in a feeding direction. The sliding contact portion is disposed on at least one end of the opening cover in the width direction, and exposed to an outside of the sheet feeder when the feed tray is in the first position.
