Abstract: A conveying device includes a first guide section, a second guide section, and an urging section. The second guide section has a guide center portion and pivots about the guide center portion. The second guide section is pivotable between a guide position and a separation position. The guide position is a position in which the second guide section is located when a conveyance path of a sheet is formed between the second guide section and the first guide section. When the second guide section is in the guide position, the urging section urges the second guide section in a first pivot direction.

Abstract: The sheet feeding device includes a feed roller, a separation pad and a guide part. The feed roller is configured to feed a sheet by being rotated while coming into pressure contact with the sheet. The separation pad is configured to form a separation nip by being in pressure contact with the feed roller and to separate the fed sheet at the separation nip. The guide part is configured to guide a leading edge of the sheet to the separation nip. The apex part is formed along a feeding direction of the sheet on both outer sides of the feed roller in a width direction perpendicular to the feeding direction. The apex part projects in a direction closer to the feed roller than an extension line of the separation nip between a pressure contact position of the feed roller and the sheet and the separation nip.

Abstract: A fixing device includes a heating belt, a pressing roller, a pressing member and a cap. The pressing member faces an inner circumferential face of the heating belt via a lubricant. The cap is rotating together with the heating belt. The cap has a disk part, a cylindrical part, a gear and a hole part. The cylindrical part has an inner circumferential face coming into contact with the outer circumferential face of the heating belt. The gear is formed integrally with an outer face of the disk part. The hole part penetrates from the inner circumferential face of the cylindrical part to a face between adjacently disposed teeth of the gear. The lubricant flowed from the inner circumferential face of the heating belt to the outer circumferential face of the heating belt flows to a tooth surface of the gear through the hole part.

Abstract: A conveying roller unit comprises a first unit, a second unit, and a lock mechanism. The first unit comprises: a roller section; and a hollow cylindrical holder section. The second unit can be removably mounted to the first unit, and comprises: a second connection section; a rod section inserted into the holder section. The lock mechanism includes: a first engagement section provided on the inner circumferential surface of the holder section; a second engagement section provided on the outer circumferential surface of the rod section; and a urging member for pressing the second unit in the direction in which the rod section comes out of the holder section. The urging member maintains the first engagement section and the second engagement section in an engaged state and restricts the position of the second unit relative to the first unit in both the circumferential direction and the rotation axis direction.

Abstract: An image forming apparatus includes a first conveying path, a second conveying path, a detector, a conveyance guide member and an interlock mechanism. The first conveying path communicates the second conveying path through which a sheet supplied from a supply part is conveyed. The detector detects whether or not the sheet is present in the first conveying path. The conveyance guide member composes the second conveying path and one end part thereof is pivotally supported so as to be able to open/close the second conveying path. The interlock mechanism interlocks the detector with the opening/closing operation of the conveyance guide member. The detector detects the opening/closing operation of the conveyance guide member.
