An image forming apparatus includes an apparatus body having an opening portion, an opening/closing member, a first unit configured to be attachable to and detachable from the apparatus body via the opening portion, a second unit configured to be attachable to and detachable from the apparatus body via the opening portion, an exposure unit provided in the apparatus body, a shutter member provided in the apparatus body and configured to move to a blocking position and a non-blocking position, and an interlocking mechanism provided in the apparatus body and configured to operate in an interlocking manner with the first unit, the second unit, and the opening/closing member. The interlocking mechanism is configured to position the shutter member at the non-blocking position in a state where the first unit and the second unit are attached to the apparatus body and the opening/closing member is positioned at the closed position.

An information processing method performs steps for an information processing apparatus to communicate with an image forming apparatus having first and second sheet output sections. The second sheet output section can be switched between a close position to serve to guide a sheet to the first sheet output section, and an open position not to guide the sheet to the first sheet output section but to stack the sheet. The method inputs a type of sheet, acquires information indicating whether the second sheet output section is in an open or closed state, and transmits image information to the image forming apparatus. When the sheet type recommends the sheet be output to the second sheet output section and the second sheet output section is in the closed state, a message is output to prompt to switch the second sheet output section into the open position before the image information is transmitted.

In a case where a sheet jam detection unit detects that a sheet jam has occurred in an image bearing member, and determines that there is no sheet P at a nip portion, a printer control unit starts cleaning by a cleaning unit without waiting for removal of the sheet P causing the sheet jam.

An image-forming apparatus is provided which enables more productive image formation. When an option unit implements a change from a second operation mode that exhibits high power consumption to a first operation mode that exhibits low power consumption while images are being consecutively formed on a plurality of recording materials, an upper limit on power that can be supplied to a fixing section is set higher than that in the second operation mode, and intervals, at which recording materials are consecutively fed, are set narrower than those in the second operation mode.
