Filed: 1987-02-10
Abstract: PURPOSE:To accurately guide a tape in spite of the size of wire-wrapping by providing a recessed part curved in a recessed shape from a line obtained by connecting the positions of guiding level difference parts in front and in the rear of a tape contact beginning part of a small contact angle. CONSTITUTION:The slightly curved recessed part 8c is provided near the tape approaching part of a small contact angle which is apart from the tape approaching part 8a of a large contact angle with a specified angle on the guiding level difference part 8 of a fixed cylinder 6.

Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To obtain an image of high image quality even in a transparent recording material (OHT) mode for an overhead projector or a gloss mode by exerting developer concentration control using a reference value in which the first and second modes for the formation of an image differ from each other. SOLUTION: In an image formation process using an OHT mode for the formation of an image on an OHT or an image forming process using a gloss mode for the formation of highly glossy image, the image is formed by carrying a recording material at a low speed. The image formation process is started after a reference-value setting process in developer concentration control. The reference-value setting process is performed each time a developing device is replaced. Then, the number of the rotations of a developer stir means is read, and a reference value is altered according to the read number of the rotations. In the case the value of measurement by a developer concentration detection means is larger than the reference value, toner replenishment is not carried out, and in the case it is equal to or lower than the reference value, toner replenishment is carried out by driving a motor M.  The developer concentration control is exerted until an amount of use of the developing device 15 reaches a specific amount.
