The supporting structure for a rod integrator 300 includes, for example, holding members 350a, 350b for holding the rod integrator 300, and supporting units 360a, 360b for supporting the holding members. Each holding member 350a contacts by its planar portions (walls) respectively with two side surfaces of the rod integrator 300 adjacent to one another. The holding member 350a has a clearance such that the holding member does not contact with the edge shared by the two side surfaces of the rod integrator 300. The supporting unit 360a includes, for example, a supporting member 361a and screw 362a. The supporting unit 360a supports the rod integrator 300 by pressing of the screw 362a along the direction of the diagonal of the rod integrator 300 via the supporting member 361a. By doing so, chipping and scratching proximate to the edge can be reduced, and soiling of the reflecting plane can be prevented.

A urinal uses a sloped interior back wall to create a specific angle between an incoming urine stream and the back wall to effect an anti-splash phenomenon which involves the contact angle hysteresis and the coanda effect, thereby at least to minimize urine splashing. The contact angle hysteresis deals with the perpendicular angles at which the urine stream comes into contact with the back wall of the urinal bowl, that is the amount of angle degrees between the angle of surface of the bowl and the angle of the urine stream at the point of contact. This angle takes advantage of the Coanda effect so as to cause the fluid (urine) to run down the surface of the back wall to the bottom of the urinal, rather than splashing back. The Coanda effect is the tendency of a fluid jet to stay attached to an adjacent curved surface that is very well shaped. In one embodiment, the interior back wall is vertically sloped towards the user, at an angle greater than 20° from the vertical (e.g., 30° to accommodate a 60° urine stream), and the back wall may be further curved from side to side. In an other embodiment, the interior back wall has a undulated top-to-bottom or vertical contour.

In the case that the electrical resistance of the contact transfer body 15 varies with the variation of the operating environment, the variation of the value of the electrical resistance is detected by the transfer body resistance detecting section and the applying time of the transfer cleaning bias is appropriately varied by the cleaning bias control section 23 based on the detected result. When the operating environment varies to a high temperature condition or to a high humidity condition, the applying time of the transfer cleaning bias is shortened by the cleaning bias control section 23, and the continuation of the conventional overdischarged condition is avoided. Therefore, even when the value of the electrical resistance of the contact transfer body 15 varies according to the variation of the operating environment, the image can be formed with a high degree of quality and the shortening of the service life of the image carrier can be prevented.
