The power source board is arranged at a lower side on the back side of the main body of the image forming apparatus. The load control board is arranged at an upper side in a vertical direction of the power source board in such a manner that the load control board does not overlap with the power source board. For a board and load at a lower side when viewed from a load control board, a connector is arranged near the lower side of the load control board. For a board and load at an upper side of the load control board, a connector is arranged near the upper side of the load control board. Similarly, for boards and loads of right and left side, connectors are arranged near the respective right and left sides of the load control board.

Image forming apparatus

Provided is a sheet material binding apparatus capable of shortening a user's waiting time required to bind sheets through a manual operation with a movable stapler. A CPU () of a sheet material binding apparatus () monitors whether or not an image forming apparatus () can execute image formation processing. When the image forming apparatus () can execute the image formation processing, the movable stapler is arranged at a standby position close to the image forming apparatus (). When the image forming apparatus () cannot execute the image formation processing, on the other hand, the movable stapler is arranged at a position for performing the manual operation, to thereby bind the sheets through the manual operation immediately.

To simplify control of a sheet feeding/conveying system while preventing a step-out phenomenon and saving power, provided is an image forming apparatus which detects a load angle of a first motor (M) for conveying an n-th sheet (P) (where n is a natural number equal to or larger than 1). In accordance with the detected load angle, a current value for the first motor (M) for conveying sheets (P) following the n-th sheet and a current value for a second motor (M) for conveying the n-th and subsequent sheets (P) are set. Such control is executed when power is turned ON or the like.

An image forming system which is capable of, when a manual stapling process is to be carried out on sheets, reducing waiting time for a user and decreasing power consumption. The image forming system has an image forming apparatus, which forms images on sheets, and a sheet post-processing apparatus. When the sheet post-processing apparatus is to shift into a power-saving state, a movable stapler is moved to a manual stapling position. When it is detected that sheets have been set into a sheet setting unit in a state in which the image forming apparatus and the sheet post-processing apparatus have shifted into the power-saving state, the image forming apparatus is held in the power-saving state, and the sheet post-processing apparatus is returned from the power-saving state.

A sheet binding processing apparatus for avoiding the residual of binding member is provided. The sheet binding processing apparatus comprises a sheet insertion port through which a sheet bundle formed of a plurality of sheets S is inserted, a movable stapler for binding the sheet bundle inserted through the sheet insertion port, and a manual stapling sheet sensor for detecting, at a predetermined detection time interval, existence or non-existence of the sheet bundle in the sheet insertion port. When the manual stapling sheet sensor detects the existence of the sheet bundle, the sheet binding processing apparatus gives permission to bind the sheet bundle by the movable stapler.

Sheet binding processing apparatus and image forming system

An image forming apparatus including an electrophotographic process is disclosed. The image forming apparatus detects a load angle of a motor associated with conveying of an n-th sheet. In accordance with the detected load angle, current values for motors associated with conveying of the n-th sheet, a current value for a motor associated with feeding of sheets following the n-th sheet, and a current value for a motor associated with conveying of the sheets following the n-th sheet are set. Such control is executed when power is turned ON or the like.
