According to one embodiment, an image forming apparatus includes a printer, a memory, a processor, and a display. The printer forms an image according to the operation of a person. The memory stores contact history information indicating the history of contact of a person. The processor acquires information on contact infection of a virus at a site contacted by a specific person from the contact history information stored in the memory. The display shows information on the contact infection of the virus.

A developing device includes a developer roller that is rotatable about an axis, to carry a developer to a development region; a rectifier member extending in a direction parallel to an axial direction of the developer roller. The rectifier member includes a developer collecting part that is spaced apart by a predetermined distance from a surface of the developer roller, and a rectifying part to guide air from within the developing device via the developer collecting part toward an upstream side of the development region, in a rotational direction of the developer roller.

An image forming apparatus includes a transfer member, a fixing member, a guide member, and an attraction member. The transfer member transfers a developer to a medium. The fixing member fixes onto the medium the developer transferred to the medium. The guide member is disposed between the transfer member and the fixing member to guide the medium. The attraction member attracts the developer through the opening. An opening is located upstream of the guide member in a medium transport direction.

In an image forming apparatus, a drum cartridge includes a photosensitive drum, a developing device, a drum cleaner, a waste toner tube, and a flange. The waste toner tube includes a first end portion communicating with the drum cleaner and a second end portion connected to the flange. The developing device includes a protruding portion facing the flange. The cushion member is located between the flange and the protruding portion. The cushion member allows a cartridge mounting part of the developing device to move with respect to the flange in a case where the developing device moves with respect to the photosensitive drum.

An image forming device, including: a drawer movable from an inside position where the drawer is located inside a housing to an outside position where the drawer is located outside the housing via an intermediate position; a stopper movable between a first position where the stopper stops the drawer from moving from the intermediate position to the outside position and a second position where the stopper allows the drawer to move from the intermediate position to the outside position; a drum cartridge mountable on the drawer; and a toner cartridge mountable on the drawer; wherein the toner cartridge mounted on the drawer is detachable from the drawer in a state in which the drawer is located at the intermediate position, and wherein the drum cartridge mounted on the drawer is detachable from the drawer in a state in which the drawer is located at the outside position.

A drum cartridge includes: a photosensitive drum rotatable about a drum axis extending in an axis direction; a drum cleaner including a cleaning member cleaning a circumferential surface of the photosensitive drum, and a cleaning housing accommodating transfer residual toner removed from the circumferential surface of the photosensitive drum by the cleaning member; a first drum side plate supporting a first end portion of the photosensitive drum; a second drum side plate located distant from the first drum side plate in the axis direction and supporting a second end portion of the photosensitive drum; a pipe located between the first drum side plate and the second drum side plate in the axis direction and extending in the axis direction; and a conveyor device conveying the transfer residual toner from the cleaning housing to the pipe.

An image forming apparatus includes an apparatus main body, a process cartridge, a scanner unit, and a toner cartridge. The process cartridge is detachably mounted on the apparatus main body. The process cartridge includes: a photosensitive drum configured to rotate about a rotational axis extending in a first direction; and a development unit configured to supply toner to the photosensitive drum. The toner cartridge is configured to store toner. At least part of the photosensitive drum, at least part of the scanner unit, and at least part of the toner cartridge are aligned in a second direction in this order. The second direction is perpendicular to both the first direction and to a vertical direction. The at least part of the photosensitive drum, the at least part of the scanner unit, and the at least part of the toner cartridge overlap one another as viewed from the second direction.
