Image forming apparatus with high-voltage board

An image forming apparatus, comprising:

• a first unit for performing an image forming process on a sheet;
• a housing including a frame member having a first surface and a second surface opposite to the first surface, the first and second surface defining an accommodation space for accommodating the first unit;
• a second unit to be mounted on the second surface of the frame member to perform a predetermined operation as the image forming process is performed by the first unit;
• a high-voltage board to be mounted on the second surface of the frame member with the second unit located therebetween for supplying a high voltage to the first unit;
• and
• a connecting mechanism for electrically connecting the first unit and the high-voltage board to supply the high voltage to the first unit;
• wherein:
• the connecting mechanism includes a unit-side wire member extending in the accommodation space and a board-side wire member connectable to the unit-side wire member and extending outside the accommodation space;
• the unit-side wire member includes a first end portion connectable to the first unit and a second end portion opposite to the first end portion;
• the board-side wire member includes a third end portion connectable to the high-voltage board and a fourth end portion opposite to the third end portion;
• one of the second and fourth end portions serves as a first contact with a biasing shape and the other serves as a second contact which can come into contact with the first contact;
• and
• the first contact is pressed into contact with the second contact while accumulating a biasing force when the unit-side wire member and the board-side wire member are connected.
