An image forming apparatus includes a formation target that is wound around rotating bodies including a driving roller and transported by the rotating bodies including the driving roller while forming a shape having linear portions each of which forms a different angle, which is an acute angle or an angle of zero degrees, with a horizontal direction when viewed in an axial direction of the driving roller, first image forming bodies that are arranged along one of the linear portions in such a manner as to be spaced apart from each other by a first distance and that form images onto the formation target, and second image forming bodies that are arranged along another one of the linear portions, the other linear portion forming the angle larger than the angle formed by the one linear portion, in such a manner as to be spaced apart from each other by a second distance shorter than the first distance and that form images onto the formation target.

An image forming apparatus, includes: plural image forming units each including an image holding member and configured to form an image that is to be transferred to a recording medium on the image holding member using a dry toner, the number of the plural image forming units being at least five; and plural developing devices each of which is provided in each of the plural image forming units and supplied with the dry toner and a dry carrier, each of the plural developing devices including a dry toner adhering unit that has a length equal to or longer than a length of a long side of an A3 size and to which the dry toner adheres, the dry toner adhering unit being configured to cause the dry toner adhering to the dry toner adhering unit to adhere to the image holding member.

A driving transmission device includes a storage part, a fixing pin and a supporting part. The storage part has a through hole. The fixing pin rotatably supports a gear. To the supporting part, the fixing pin is fixed. A hole side chamfered portion is formed at an outside opening edge of the through hole. A shaft side chamfered portion is formed at the tip end portion of the fixing pin. A lubricant is applied to a contact area between the fixing pin and the through hole. A hole side boundary portion between an inner circumferential surface of the through hole and the hole side chamfered portion is in contact with an outer circumferential surface of the fixing pin. A shaft side boundary portion between an outer circumferential surface of the fixing pin and the shaft side chamfered portion faces the hole side chamfered portion with a gap.

An image forming device includes first and second discharge rollers, and first and second covers. The first cover is pivotally movable between first closing and opening positions about a first pivot axis. In the first opening position, the first cover supports a sheet from the first discharge roller. The second cover is pivotally movable between second closing and opening positions about a second pivot axis. In the second opening position, the second cover guides a sheet from the second discharge roller. In the first closing position, one end portion of the first cover is farther from the second cover. In the second closing position, another end portion of the second cover is farther from the first cover. The first pivot axis is at the one end portion of the first cover. The second pivot axis is at the another end portion of the second cover.

An image forming apparatus includes a casing in which multiple units are disposed. The casing has a front wall having a first opening and a stepped wall having a second opening. In the casing, an exposure unit is disposed in front of an image forming unit, above the first opening, and above a sheet loading section, and a fixing unit is disposed above the image forming unit. The exposure unit is disposed with a first gap between the exposure unit and the image forming unit, and the fixing unit is disposed with a second gap between the exposure unit and the image forming unit. The first gap and the second gap constitute a ventilation channel for distributing outside air flowing into the casing through the first opening to the second opening.

An image forming apparatus includes an image forming target looped around plural rotators including a driving roller, having at least one straight portion that is shaped straight when viewed in an axial direction of the driving roller, and transported by the driving roller and the rotators, and three or more image formers arranged along the straight portion and configured to form images on the image forming target. An adjacency distance along the straight portion between the image formers adjacent to each other on the straight portion is an integral multiple of an outer peripheral length of the driving roller. The adjacency distance at a downstream end is shorter than the adjacency distance at an upstream end, and one of the adjacency distances is equal to or shorter than the adjacency distance that is relatively on an upstream side.
