Abstract: A development device includes a rotational member and a housing. The housing includes a lower housing and an upper housing. The lower housing has an opened upper face. The upper housing has an opened lower face. A first edge portion around the opened upper face has a recess, a first contact face and a first opposite face. The first contact face is formed inside the recess. The first opposite face is formed outside the recess. A second edge portion around the opened lower face has a protrusion, a second contact face and a second opposite face. The protrusion is fitted into the recess. The second contact face comes into contact with the first contact face. The second opposite face opposes the first opposite face. The first and second contact faces are higher than the first and second opposite faces. The recess and the protrusion are adhered with an adhesive.

Abstract: An image forming apparatus includes an output shaft including a columnar part and a D cut part connected to the columnar part and having a D section, and an electromagnetic clutch including a cylindrical member fitted to the output shaft. The image forming apparatus further includes a key member. The key member includes a conductive member. When the D cut part of the output shaft is employed as an insertion tip side and the output shaft has been inserted to the cylindrical member from one side in an axial direction, the key member is configured to fill a space between the sectional circular part of the inner peripheral surface of the cylindrical member and the D cut part of the output shaft.

Abstract: A lighting device includes a light source, a light guide, a light guide cover, and a unit frame. The light guide is in a bar form and, while guiding light that has entered from the light source along the axial direction, sends forth the light. The light guide cover holds the light guide. The light guide cover is attached to a unit frame. The light guide cover includes a main body portion and a plurality of light guide holding portions provided along the longitudinal direction of the main body portion and holding the light guide at a plurality of places, and a plurality of guide engaging portions provided along the longitudinal direction of the main body portion. The unit frame has a cover fitting face to which the light guide cover is fitted and a plurality of cover guides with which a plurality of guide engaging portions engage respectively.

Abstract: A development device includes a rotational member and a housing. The rotational member rotates around an axis. In the housing, the rotational member and a toner are stored. The housing includes a lower housing and an upper housing. The lower housing has a concave first storage part having an opened upper face. The upper housing has a concave second storage part having an opened lower face. The first storage part has a first edge portion around the opened upper face. The first edge portion has a first contact face. The second storage part has a second edge portion around the opened lower face. The second edge portion has a second contact face coming into contact with the first contact face. The first contact face and the second contact face are contained in a single plane along respective entire circumferences.
