A sheet guide of an image forming apparatus includes a first upstream guide member and a first downstream guide member. The first upstream guide member includes an upstream front guide surface and an upstream rear guide surface. The first downstream guide member includes a downstream front guide surface and a downstream rear guide surface. The downstream front guide surface intersects with an imaginary plane formed by extending, toward a downstream side in a conveyance direction of a sheet, the upstream rear guide surface. The upstream front guide surface intersects with an imaginary plane that is formed by extending, toward an upstream side in the conveyance direction, the downstream rear guide surface. When viewed from a direction perpendicular to the upstream rear guide surface, an edge portion of the first upstream guide member on the downstream side is inclined with respect to a width direction perpendicular to the conveyance direction.

An image forming apparatus includes an image carrier, a charging device, a developing device, a transfer member, a registration roller pair, a conveyance guide, and a first cover member. The conveyance guide includes a first conveyance guide opposing one surface of a recording medium conveyed from the registration roller pair to a transfer nip, the one surface being on a side of image carrier, and a second transfer guide opposing another surface of the recording member, the other surface being on a side of the transfer member. The first cover member covers an area along a peripheral surface of the image carrier from the developing device to the transfer member, and forms a substantially sealed space together with the image carrier, the developing device, the transfer member, the registration roller pair, and the transfer guide. A through hole is formed in the first transfer guide.

A sheet conveyance apparatus includes a sheet conveyor configured to convey a sheet, a guide configured to form a conveyance path through which the sheet is conveyed by the sheet conveyor, and a sensor disposed on a same side as the guide with respect to the conveyance path. The guide includes a retracted portion disposed over a first region in a sheet width direction perpendicular to a sheet conveyance direction, the retracted portion being retracted with respect to a second region of the guide in the sheet width direction so as not to come into contact with the sheet passing through the conveyance path, the first region including a detection region of the sensor in the sheet width direction, the second region being a sheet passing region of the sheet in the sheet width direction excluding the first region.

An image forming apparatus includes a first roller, a second roller arranged downstream of the first roller in a sheet conveyance direction, the second roller including a rotation shaft and a roller body supported by the rotation shaft, a third roller arranged downstream of the second roller in the sheet conveyance direction, a first support member configured to rotatably support the first roller, a second support member configured to rotatably support the third roller, and a bearing member configured to rotatably support an end portion of the rotation shaft. The bearing member includes a first positioning portion configured to position an end portion of the first support member and a second positioning portion configured to position an end portion of the second support member.

An image forming apparatus includes a first side plate, a second side plate, a first connecting member, the first connecting member being secured to the first side plate at a first securing portion and being secured to the second side plate at a second securing portion, and a frame, the frame being sandwiched between the first side plate and the second side plate and being secured to the first side plate and the second side plate. At least one of the first side plate and the first connecting member is deformed to form the first securing portion, and at least one of the second side plate and the first connecting member is deformed to form the second securing portion.

An image forming apparatus includes a housing, an attachable and detachable device, a cover member, and a rotation angle restricting member. The housing has an opening and an attachment section. The attachable and detachable device is attachable to and detachable from an inside of the housing via the opening. The cover member is rotatably supported by the housing and closes or opens the opening. The rotation angle restricting member restricts an allowable rotation angle that indicates an angle at which the cover member is rotatable. The rotation angle restricting member is attachable to and detachable from the attachment section. The allowable rotation angle of the cover member is restricted when the rotation angle restricting member is attached to the attachment section. Restriction of the allowable rotation angle of the cover member is released when the rotation angle restricting member is detached from the attachment section.

An image forming apparatus includes: a transport member that transports a medium; a storage that is disposed below the transport member in a gravitational direction, and that stores the medium which is delivered by the transport member and falls into the storage; a supporter that is provided in the storage, and that has an upper end disposed below the transport member in a gravitational direction, and that allows the medium to be stored with a front end of the medium in a discharge direction matching a lower end of the medium in a gravitational direction; and a guidance member that is disposed in the supporter with the medium interposed between the guidance member and the supporter, and that guides the medium which falls to the supporter.

Disclosed is a sheet conveyance guide unit. The sheet conveyance guide unit includes a first sheet guide member which is of a sheet-like shape and which guides a sheet on which an image is formed and a second sheet guide member which is of a sheet-like shape and which is attached on a sheet guide surface of the first sheet guide member. A length of the second sheet guide member in a direction which crosses a sheet conveying direction is smaller than that of the first sheet guide member.

A sheet discharge device of the present invention includes discharge rollers configured to transport a sheet in a predetermined transport direction and to discharge the sheet to a discharge tray, and an upper discharge tray disposed above the discharge tray with a space being interposed therebetween. A bottom face of the upper discharge tray that faces the discharge tray includes a guide rib extending in an oblique direction inclined relative to the transport direction.

An image forming apparatus includes an image carrier, a developing section, a transfer section, a pre-transfer conveyance passage, and a guide member. The pre-transfer conveyance passage allows conveyance of the sheet from the developing section to the transfer section. The guide member defines a side of the pre-transfer conveyance passage that faces the transfer surface. The guide member includes: a guide body having a guide surface that faces the transfer surface of the sheet; and a tip section having a curved portion joining an end edge of the guide body, and a distal edge that is on a downstream side in the conveyance direction and faces the image carrier. The distal edge is located at such a position as to allow the transfer surface of the sheet to lie at a space therefrom when a leading end of the sheet is in contact with the image carrying surface.
