发明名称 Image forming apparatus
摘要 An image forming apparatus includes: a conveyance drum which has a round cylindrical shape including an outer circumferential surface having a medium holding section, and rotates in a prescribed direction while holding a medium in tight contact on the medium holding section so as to convey the medium in a circumferential direction; a pressing device which presses the medium against the medium holding section so as to establish tight contact between the medium and the medium holding section, when causing the medium to make tight contact with the medium holding section; a holding force generating device which generates a holding force that holds the medium on the medium holding section; and a liquid ejection head which ejects a liquid onto the medium held on the medium holding section, wherein: the conveyance drum has a level difference section which is provided on at least one side, in an axial direction of the conveyance drum, with respect to a central portion in the axial direction of the conveyance drum, the level difference section having a larger diameter than the central portion so as to project beyond an outer circumferential surface of the central portion; and the level difference section has a length, in the circumferential direction, smaller than a length of the medium holding section in the circumferential direction.
