When media that have not been subjected to the binding process are stacked on the medium ejection portion, the pressing member and the media are brought into contact with each other. When media that have been subjected to the binding process are stacked on the medium ejection portion, the pressing member and the media are disposed further away from each other than when media that have not been subjected to the binding process are stacked on the medium ejection portion.

An image forming apparatus includes plural medium transport paths that branch at a predetermined branching position and along which a medium is transported in a curved state; a switching member disposed at the branching position and including a guide surface that allows the medium to be transported along one of the medium transport paths, the switching member switching between the medium transport paths; an output unit that outputs the medium toward a stacking portion, on which the medium is to be stacked, while corrugating the medium; and a guide portion that guides the medium from the branching position toward the output unit in a region in which the medium is corrugated.

Image forming apparatus

A binding device includes a sheet-bundle forming unit; a binding unit that executes a series of operation including inserting a wire into a sheet bundle and bending the wire; a power supply unit; a detector that detects a first timing for transitioning from bending operation to recovery operation; a first timekeeper that measures time from a start point of the series of operation to a first time point, which is an end of a scheduled first-timing detection period; a unit-of-processing manager; and a supply power controller. When the first time point is reached before detection of the first timing, the controller causes the power supply unit to adjust the electric power before the first timing is reached, such that the first timing is detected before the first time point in the series of operation for a second bundle belonging to the same unit of processing as a first bundle.

A decoding device checks whether there is free space in each of channel-by-channel buffers, specifies a channel corresponding to a buffer having free space as an input channel for receiving an input of compressed data, analyzes codes of the compressed data received through the input channel, and detects a delimit position in the compressed data on the basis of a result of the analysis. The decoding device expands the compressed data received through the input channel, and sorts the expanded data so as to be stored in the buffer corresponding to the input channel. The decoding device cancels specification of the input channel in accordance with detection of the delimit position, and checks whether there is free space in each of the channel-by-channel buffers, and then specifies a channel corresponding to a buffer having free space as a next input channel.
