An image forming apparatus includes a transfer unit that transfers an image onto an object by making contact with the object; an attachment table to which the object is attached and that changes a height thereof in accordance with force by which the transfer unit makes contact with the object; and a transport unit that transports the attachment table to which the object has been attached along a transport path.

An image forming apparatus (100) includes: an intermediate transfer belt (15B) provided in a body housing (3); an opening/closing unit (30); a second transfer roller (152) provided in the opening/closing unit (30) and in contact with the intermediate transfer belt (15B) when the opening/closing unit (30) is closed; a guide member (31) provided in the opening/closing unit (30) turnably and guiding a sheet to a contact area between the intermediate transfer belt (15B) and the second transfer roller (152); a conductive sheet (32) covering the guide member (31); and a conductive spring (33) provided in the opening/closing unit (30) and biasing the guide member (31) toward the intermediate transfer belt (15B) via the conductive sheet (32) to press the guide member (31) to the body housing (3), wherein when the opening/closing unit (30) is opened, the guide member (31) is in contact with the conductive spring (32) by gravity.

A method for controlling a printing system including a printing apparatus configured to execute a printing process on a sheet, and a static elimination apparatus configured to perform a static elimination process on the sheet printed by the printing apparatus, includes switching, depending on a printing surface of the sheet printed by the printing apparatus, a polarity of a voltage to be applied to a first static elimination unit provided on an upper surface side of the sheet printed by the printing apparatus to positive or negative, and switching, depending on the printing surface of the sheet printed by the printing apparatus, a polarity of a voltage to be applied to a second static elimination unit provided on a lower surface side of the sheet printed by the printing apparatus to positive or negative.

An image forming apparatus includes an operation unit configured to allow selection between a first mode for forming an image on a first recording material which is leather and a second mode for forming an image on a second recording material which is paper, a first placement portion on which a recording material is to be placed, a second placement portion on which a recording material is to be placed, an image former configured to form an image on a recording material, and a display, wherein a first curvature of a first conveyance path from the first placement portion to the image former is smaller than a second curvature of a second conveyance path from the second placement portion to the image former.

An image forming apparatus includes a transfer portion; a fixing portion; a detection unit that is capable of detecting a deflection amount of the recording material; and a controller configured to control a conveying speed of the fixing portion. The detection unit has a contact portion and a detection portion, and the contact portion is movable to a first position and a second position. The controller moves the contact portion from the second position by outputting the signal for setting the conveying speed to a second speed larger than the conveying speed when the contact portion is located at the second position, and the controller determines an abnormal state when the contact portion is located at the second position and an output time of the signal is longer than or equal to a predetermined time.
