摘要： An image-forming device includes a casing, a photosensitive drum, a transfer roller, a first guide member, and a second guide member. The first guide member is disposed upstream of the transfer point between the photosensitive drum and the transfer roller in a conveying direction of the recording medium and selectively movable between a first position and a second position. The second guide member is disposed between the first guide member and the transfer point and selectively movable between a third position and a fourth position farther from the photosensitive drum than the third position. The second guide member is movable in association with the movement of the first guide member in such a manner that when the first guide member is disposed in the first position, the second guide member is disposed in the third position for guiding the recording medium received from the first guide member to move toward the photosensitive drum.

摘要： An image forming apparatus includes a photoconductor member, and a transfer roller disposed to face the photoconductor member and allow the developer image to be transferred to a transfer-receiving member. A fixing device disposed downstream from the photoconductor member in a conveying direction and configured to fix the image formed on the transfer-receiving member, and a conveying path forming member disposed between the photoconductor member and the fixing device, and that forms a conveying path from the photoconductor member to the fixing device. The conveying path forming member includes first and second members which respectively extend from/to the photoconductor member to/from the fixing device. The second member crosses a second line which perpendicularly crosses a first line, which connects axes of the photoconductor member and the transfer roller, and passes through a contact area in which the photoconductor member and the transfer roller are configured to contact each other.
