An image formation device for executing a printing job to form a toner image on a record sheet includes: an operation panel configured to move between a first position at which the operation panel protrudes from a front of a device body and a second position at which the operation panel is retracted to a device body side with respect to the first position; an acquisition device configured to obtain state information indicating a state of the device body; and a hardware processor configured to determine, based on the obtained state information, whether the state of the device body is a state requiring a user access to the device body or a state of accessing to the device body and to retract the operation panel to the second position when a determination result is positive.

An image forming apparatus includes a first removable member that includes an image carrying member and that is removably supported with respect to a body of the image forming apparatus; a first guide portion that is provided at a lower surface of the first removable member; a second guide portion that is provided at the first removable member; a first guiding portion that is provided at the body of the image forming apparatus and supports the first guide portion when the first removable member is placed on the first guiding portion; and a second guiding portion that is provided at the body of the image forming apparatus, in which, when the first removable member moves in a mounting direction from a state in which the first guide portion is supported by the first guiding portion, the second guiding portion contacts the second guide portion and guides the second guide portion.

An apparatus body includes a housing, a drawer, a push-out mechanism, and a positioner. The drawer is attachable to and detachable from the housing. The push-out mechanism pushes out the drawer by a predetermined amount from a setting position at which the drawer is positioned in the housing. The positioner positions the drawer at the setting position in the housing. The positioner includes a fitting hole disposed in one of the housing and the drawer and a positioning pin disposed in the other of the housing and the drawer. The positioning pin positions the drawer at the setting position in the housing in response to fitting of the positioning pin into the fitting hole. The positioning pin and the fitting hole each have a form that releases the fitting in response to pushing out of the drawer by the predetermined amount from the setting position.

An image-forming apparatus includes, in a body having a predetermined house, an image-reading unit and an image-forming unit that is configured to form an image read by the image-reading unit. A discharge portion is configured to discharge a sheet on which the image was formed onto a discharge tray. An intra-apparatus-discharge space is formed in the body between the image-reading unit and the image-forming unit. The housing includes therein a consumption article mounting portion in which a consumption article used by the image-forming unit is mounted. At least a portion of a surface of the housing at a region of the consumption article mounting portion has a light-transmissive property. When the consumption article is consumed and needs to be replenished, the operator can visually check the region of the consumption article mounting portion in the housing from the outside of the body through the transparent portion.

An image forming apparatus includes a body casing, a pressing member, a process cartridge, and a drawer. The body casing includes a positioning member. The pressing member is disposed inside the body casing. The process cartridge includes a photosensitive drum. The drawer is configured to support the process cartridge and to move, in a sliding direction orthogonal to an axis direction of the photosensitive drum, between an inside position that is a position inside the body casing and an outside position that is a position outside the body casing. The process cartridge includes an engagement portion and a spring. The engagement portion is configured to be positioned by the positioning member. The spring is configured to be pressed by the pressing member such that the engagement portion is pressed toward the positioning member.

An image forming apparatus includes: a drawer movable between an inner position and an outer position and supporting a first cartridge including a first photosensitive drum and a first discharge part and a second cartridge including a second photosensitive drum and a second discharge part; and a waste toner box including a first coupling part coupled with the first discharge part and a second coupling part coupled with the second discharge part, in a state where the first cartridge and the second cartridge are supported by the drawer at an inner position and the waste toner box is mounted to the apparatus main body, the waste toner box being movable between a first/second position where the first coupling part and the first discharge part are coupled/decoupled and the second coupling part and the second discharge part are coupled/decoupled.

An image forming apparatus includes a developer container to and from which the replenishment container is attachable and detachable and which includes an accommodating portion that accommodates developer and a replenishment port, an agitation, an opening/closing member configured to be movable between a closed position and an open position, a drive source for driving the agitation member, and a control portion configured to control the drive source, wherein the apparatus is configured such that image formation is not possible when the opening/closing member is at the open position, and the agitation member is capable of driving in a case where the opening/closing member is at the open position.

An image forming apparatus includes a tray movable between a housed position and a drawn-out position. The tray includes a frame having two side portions extending in a moving direction of the tray and to which a developing cartridge is detachably attachable, an image bearing member supported by the frame so as to face a developer bearing member when the developing cartridge is attached to the frame, a charging unit, a tray-side metal terminal electrically connected to a memory medium when the developing cartridge is attached to the frame, and a tray guide portion provided on the two side portions along a moving direction of the tray. A body-side metal terminal is provided in a body, which includes a rail portion to face the tray guide portion and enable the tray to move. The tray-side metal terminal contacts the body-side metal terminal at a position below the tray guide portion.

An apparatus body includes a housing, a drawer, a push-out mechanism, and a positioner. The drawer is attachable to and detachable from the housing. The push-out mechanism pushes out the drawer by a predetermined amount from a setting position at which the drawer is positioned in the housing. The positioner positions the drawer at the setting position in the housing. The positioner includes a fitting hole disposed in one of the housing and the drawer and a positioning pin disposed in the other of the housing and the drawer. The positioning pin positions the drawer at the setting position in the housing in response to fitting of the positioning pin into the fitting hole. The positioning pin and the fitting hole each have a form that releases the fitting in response to pushing out of the drawer by the predetermined amount from the setting position.

An image forming apparatus includes: a housing; a process cartridge including a photoconductive drum and a developing roller; a toner cartridge containing toner; and a drawer movable between an inner position and an outer position. The process cartridge includes a lock member movable between a lock position at which the lock member locks the process cartridge to the drawer, and a release position at which a lock between the process cartridge and the drawer is released. The lock member is located at the lock position in a state in which the process cartridge is mounted to the drawer, and the toner cartridge is mounted to the process cartridge. The lock member is located at the release position in a state in which the process cartridge is mounted to the drawer, and the toner cartridge is removed from the process cartridge.
